The goal of this article is not to pick one cartridge as the best; there are plenty of articles and forums out there endlessly debating the topic. Instead of throwing ourselves into a circular argument, we are going to look at the performance specs of these two cartridges so that we can have a better understanding of in which situation these cartridges will excel.
For two hunting cartridges with an impeccable track record such as these, they both deserve the recognition for their abilities in the field. So, let’s first take a look at the origins of these cartridges and how their design specifications match up.
.300 Win Mag vs .308: A Brief History
.300 Winchester Magnum
The .300 Win Mag uses a 30-cal bullet that came into production by Winchester in 1963. When comparing to other popular hunting rounds, the .300 Win Mag is a newcomer.
This cartridge can be packed with large amounts of powder giving it a huge advantage in velocity and in turn, the ability to carry a large amount of energy over a greater distance. The cartridge is also able to take a variety of bullet weights. Most weights are within the 150-200 grain range, but there are several lighter and heavier rounds available. It is also available in a wide array of bullet styles which gives it a lot of versatility.
This is an extremely popular cartridge for long-range shooters including those chasing big game. The .300 Win Mag is not only a hunting cartridge but is also favored by long-range competitive shooters. While this cartridge has been and is still used in sharpshooting corners of the military, the majority of its action is found in the hunting world.
The .308 Winchester is a cornerstone of the American hunting world, though it has a strong history in other shooting circles. The .308 was introduced by Winchester in 1952 where it gained an immediate following in the hunting community. Soon after, the military adopted the cartridge and modified it to produce the 7.62×51 NATO round which replaced the .30-06 chambered rifles in Vietnam.
Even though widespread use of the .308 in the infantry was short-lived, it shows no sign of faltering in the hunting world. The larger weight bullets and casing provide a cartridge that can give excellent range for most hunting scenarios and provide more than enough stopping power for medium to large size game.
This is a highly popular cartridge and is widely available with numerous options for bullet weights and designs which further increases its versatility in the field.

|Max Pressure (SAAMI)||64,000psi||62,000psi|
If we take a look at the basic specs of these two cartridges, we can see some major differences. Both of these use the same diameter bullet, but we will see by looking at performance specs that these two cartridges do not behave similarly regardless of using the same caliber bullet. The major difference is in the case dimensions. The neck diameter of the two casings are slightly different with the .300 WM being a couple of hundredths of an inch smaller than the .308 Win. The .300 WM has a wider base diameter and a significantly longer case length than the .308 Win which results in a much more voluminous case that allows more powder and can take higher pressure than the .308 Win. This is where the differences we will see in the ballistics, and other performance categories originate.
To gain some insights into the 300 Win Mag vs 308 arguments, we have chosen five rounds of each cartridge for comparison. We will take a look at several ballistics categories such as the velocity and trajectory as well as other important characteristics such as stopping power and generated recoil. Again, our goal in doing this is not to determine which cartridge is better but in what situations each cartridge might be better suited.
Even with ten selected rounds, we acknowledge that this is still a small sample size compared to what is on the market. We are still confident that the conclusions we can reach give us a clear window into these two cartridges. We have selected five popular rounds each that are most often used in the field so even though there are a lot more options out there, what matters for most marksmen and hunters is what is most available. Another reason we are confident is that we have selected a good range of available rounds with varying bullet weights and designs. We have listed these rounds below.

These ten rounds are all available factory loads that you can find and purchase at just about any major retail store. Your cartridge of choice might not be on this list, and that doesn’t mean that we don’t think it deserves to be or is an inferior cartridge in any way. In reality, we are just limited in space and had to draw a cutoff line.
All of the data that you are going to see in this article has been taken from the manufacturer’s website or generated from online ballistic generators. Because these are computer generated numbers, they may not be the exact numbers you would get from firing these rounds through your platform. This is common since just about every gun has its own ballistics profile. Because all of this data is computer generated, the trends in this article hold up to data generated in the field. It is also preferred for comparing cartridges because you do not have the variations from firing rounds live and measuring the various ballistic categories
So, let’s jump into the fun stuff.
What we are going to look at for recoil is the actual force that is generated by igniting the powder within the cartridge. Sending bullets downrange at such high velocities that both of these cartridges achieve also generates a significant amount of force that we feel and call recoil or kick.
We can’t quantify the recoil you will feel when firing a rifle chambered for one of these cartridges. This is known as “felt recoil,” and a lot of other factors influence this such as barrel length and stock design. Because of this, we will stick to the measurable ft.lb force generated. It still gives you a good idea of the amount of kick you will have to deal with and is a good way to quantify recoil between two cartridges such as the 300 Win Mag vs 308.
First, let’s look at a general comparison of recoil force between the 308 and 300 WM that was generated by the recoil calculator as an average of several rounds (Graph 1). Both cartridges generate over 20ft.lbs of force, so they have significant kick. This amount of recoil is considered enough to cause flinching for a lot of shooters which is going to greatly influence your accuracy. A lot of times when people blast a round and cartridge for inaccuracy it is often because the recoil is too much and causing them to flinch as they pull the trigger. Comparing the two, the 300 Win Mag generates a little over six lbs of force more than the .308 Win. While six ft.lbs of force might not seem like a huge difference, it is pretty significant when associated with recoil. Whether or not this amount of difference is going to impact you and your shot we can’t know. It takes you firing a few rounds of each cartridge to gain an idea. And of course, the amount of recoil generated can vary from round to round for each cartridge.
Let’s take a look at our eight rounds and see if this trend continues when we compare several different rounds of each cartridge (Graph 2).
There is some variability in recoil generated for each cartridge depending on the bullet weight and muzzle velocity that is given. The powder loads most likely differ between the rounds as well although that data is not given and we took the liberties of using the same powder loads for each round of the same cartridge based on load data from Nosler. These powder charges were conservative on our end since these are factory loads. We do see the same trend of the .300 Win Mag generating more recoil than the .308 rounds throughout the graph With all of the .300 Win Mag rounds generating between 27 and 32.5ft.lb of recoil energy while the .308 Win rounds fell between 22 and 23.5ft.lb of recoil energy.
Ballistics is an extremely important component to effectively comparing two different cartridges. Ballistics cover a variety of topics including ballistic coefficients, which tell us a lot about how the bullet will perform in other categories and how well bullets resist environmental factors, bullet velocity, and bullet trajectory. By looking at all of these different components, we will have a much better understanding of which scenarios either one of these cartridges will be better suited. And as we go through these various categories, keep in mind that they all play off of one another and all influence the performance and profile of each round. We look and compare each individually for the sake of simplicity, but all factor into the performance of the bullet and the cartridge as a whole.
One of the main reasons to look at velocity is because it has been shown to correlate with accuracy. The faster a bullet travels, the less effect wind and gravity have on the bullet. The less these outside influences can affect the bullet, the truer the flight path and more accurate the round will be. Again, there are other factors that go into accuracy, most importantly the person on the smart end of the gun, but accuracy is a major variable in the overall equation.
Velocity is also important in the terminal ballistics of a round as it influences the bullet’s energy as well as how the bullet will expand on impact. As we mentioned in the introduction of these cartridges, you might see rounds on the internet touting much hotter velocities than these factory loads. The reason is usually that they are hand loaded and packed with a lot more powder than the manufacturer is going to load. While increased velocities can improve the performance of a bullet, there is a fine line you begin to walk with a hot load. Hot loads paired with the wrong rifle twist can cause a tumbling and bumbling bullet.
Because these are popular hunting and long-range shooting rounds, accuracy is a critical component, and we will take a look at how these two cartridges match up with each other from the muzzle to 500 yards (Graph 3).
We do see some overlap in bullet velocities when looking at the 300 Win Mag vs 308. When just looking at the .300 Win Mag rounds. The lighter bullets show a higher muzzle velocity and higher velocity downrange than the heavier bullets. We see that same trend with the .308 Win rounds as well.
The .300 Win Mag rounds have a slight advantage in velocity right out of the muzzle out to 500 yards. If we were to look at the averages of these rounds, we would see a little over 200ft.sec difference between the 300 WM vs 308 and this difference increases slightly as the rounds move downrange. There is some overlap between rounds of each cartridge from the muzzle to 200 yards but from that mark out to 500 yards we see a visible grouping of the two rounds with the .300 Win Mag rounds showing higher velocities. There are several .308 rounds that compete with the 300 WM rounds, and if other categories are to your liking and you decide to go with a .308, there are rounds with more than enough velocity for you. What we also see is that all of these rounds remain at velocities over 2,000ft.sec at 300 yards and are still supersonic even out to 500 yards. This is more than enough velocity for proper terminal ballistics.
While the .300 Win Mag rounds have heavier weighted bullets, only slightly, we don’t see slower bullet velocities compared to the .308 because of the higher powder loads that can be used. This is one of the main reasons we see a lot of similarity between the two cartridges velocity. Of course, we are only looking at five rounds for each cartridge, and with a wider sample size, we might see a more pronounced higher velocity for the .300 Win Mag.
Ballistic Coefficient (BC)
A ballistic coefficient is a number that you will run across when doing any research on cartridges. The BC is derived from an equation and basically, gives you an idea of how streamlined the bullet is. The higher the BC, the less susceptible the bullet is to drag and wind drift. For taking shots at game in less than ideal weather conditions at 100+ yards, the BC is an important factor. Theoretically, a higher ballistic coefficient is going to mean a bullet where fewer adjustments are needed for proper shot placement. If you expand on that, a bullet with a high BC should be more accurate excluding all other factors.
We have collected the BCs for all ten rounds used in this comparison (Graph 4).
We see that the 300 Win Mag has a higher BC than the .308 rounds on average. While there is variation from round to round, this trend will hold up with just about any rounds of the two cartridges you can find. When we look at the numbers, we see several .300 Win Mag rounds that crack the .5 mark while only one of the .308 Win rounds exceeds this mark. In fact, there are two .300 Win Mag rounds that break the .6 mark, which is an excellent ballistic coefficient for factory loaded rounds for any cartridge types. We will come back to this section when we talk about application, but keep this in mind as we move on to bullet trajectory.
Bullets, once fired downrange, do not move in a flat line. They have a parabolic trajectory, and as they move downrange, the bullet loses altitude. Most centerfire rifle cartridges have a pretty flat trajectory out to 200 and even 300 yards. Past this point bullet drop begins to be an issue. With any cartridge, you want to see a flat trajectory. For hunting, especially for long-range shots, a flat trajectory makes aiming and connecting on a shot much simpler. Even with today’s optics understanding the trajectory of the round you are using is critical to success.
Before we move into looking specifically at the short and long-range trajectory, we wanted to compare two very similar rounds from each cartridge made from the same manufacturer, containing the same bullet style. These two rounds also have similar ballistic coefficients. By doing this for the 300 Win Mag vs 308, you can get a clear picture of how the trajectories of these two cartridges compare (Graph 5).
Even with a lighter bullet of the .308, there is a discernible difference in trajectory between these two cartridges. From around 180 yard mark, the 300 Win Mag begins to show a flatter trajectory than the .308 Win. This trend continues with the difference between bullet drop increasing as they move downrange. At the 500 yard mark, we see around 10 inches more bullet drop with the .308 Win round.
Let’s take out ten rounds and zoom into smaller sections along this yardage and look closer at these differences.
Short Range Trajectory
While the .300 Win Mag is more known for its long-range ability, the .308 is often associated with closer range and hunting in thick cover though we will see that the .308 is not too shabby when it comes to longer range shots. So, let’s take a look at the short-range trajectory and see if there is any difference (bullet drop) between our .300 Win Mag and .308 rounds (Graph 6).
Up to the 100-yard mark, where the shots were zeroed in, all of these rounds for both cartridges show minimal adjustments that would need to be made when taking a shot.
As the bullets move out to the 200-yard mark, there is still not a whole lot of difference between the two cartridges. For the most part, the rounds all fall within an inch and a half of each other. We do see some separation between the two cartridges though the overall average of the two cartridges shows the 300 Win Mag has a slightly flatter trajectory. We also see a difference of 2 inches between the flattest .300 Win Mag and the steepest dropping .308 Win round. Once the bullets get out to the 300-yard mark, there is a definite advantage for the .300 Win Mag bullets that are propelled downrange by a higher payload. At this point, the .300 Win Mag rounds show an average of 3.5 inches less bullet drop than the .308 Win rounds. While some rounds between the two cartridges are fairly similar at this range, there are several 300 WM rounds that have a much flatter trajectory, some with over 7 inches of difference.
While there is going to be variability depending on the round, both cartridges perform very similarly out to 200 yards before the .308 begins to lose altitude at a faster rate than the .300 Win Mag rounds.
Long Range Trajectory
Since we looked at short range trajectory, we also want to take a look at how these two cartridges compare when on a longer flight path. We still measure bullet drop in inches, but in this case, the test firearms are zeroed in at 200 yards (Graph 7).
And because the 300 Win Mag is one of the more popular choices for long range hunting and general shooting purposes, we are going to examine bullet drop out to 700 yards.
Up to the 300-yard mark, both of these cartridges are near identical in their trajectory for all rounds with only 2-3 inches in difference. Even though the difference is small, there is a trend towards the 300 Win Mag rounds having a flatter trajectory than the .308 Win even if it is only around an inch of difference on average. While there is a significant difference between several of the 300 Win Mag and 308 rounds at the 400-500 yard mark, there is some middle ground where the two cartridges have rounds similar in trajectory. With that being said, the average bullet drop of the 300 Win Mag rounds is still several inches less than the .308 rounds and a little over ten inches in difference at 500 yards, a pretty significant difference.
Once we get out to the 600 and 700-yard range, there is a clear distinction in the groupings of the two cartridges with the .300 Win Mag showing an average of 20 inches less bullet drop than the 308 Win rounds. At the range, the 300 Win Mag has an average of 66 inches of bullet drop while the .308 Win rounds have an average drop of 86 inches. This difference continues out to the 700-yard mark where the 300 Win Mag shows an average bullet drop of 101 inches and the .308 Win rounds show an average bullet drop of 126.5 inches.
While all of the ballistic properties are important, it doesn’t make a difference if the bullet is not carrying enough energy when it reaches the target to make a clean and humane kill. Especially when these cartridges are being used for hunting purposes. If you are deciding on a cartridge to be used in shooting competition or to just spend time on the range showing up your friends, this section might not be as important in your decision.
In this section, we are going to compare the amount of force that will transfer to the animal from the bullet on impact (ft.lb). We will also examine the penetration potential of these cartridges by looking at the sectional densities of our ten selected rounds.
While bullet energy and penetration are critical to understanding a cartridges stopping power, it is not the only component to making a round effective in dropping an animal quickly; bullet design and wound type also are important factors but are more difficult to compare quantitatively, especially when only comparing two cartridges. We will cover penetration after looking at the rounds energy. This is the reason that we have chosen bullet energy and penetration potential through the sectional density as the components for stopping power between the 300 Win Mag vs 308.
Every bullet that is fired from your rifle carries kinetic energy that becomes a physical force once it reaches the target. The main components of this energy include the velocity as well as the mass of the projectile. When the bullet reaches the target, this energy is transferred to the surrounding tissue, organs, and nerves where it causes massive damage.
If you look at hunting websites and forums, you will probably come across arguments where people are arguing the amount of energy that is needed to cleanly harvest certain animals such as deer or elk. The consensus is around 1,000ft.lb of energy for whitetail and 1,500ft.lb of energy for elk. You can find these numbers for any game animal out there. And while we agree that energy is important we also believe shot placement is as, if not more important.
Still, it’s important to have a firm grasp of what you are working with, especially if you are interested in chasing larger game.
If we look at this energy for our ten rounds for comparison of the .308 vs .300 Win Mag (Graph 8), we see that the .300 Win Mag has the edge over the .308 in bullet energy.
From the graph, we see a clear grouping of the various rounds from the two cartridges with the .300 Win Mag showing the obvious advantage in bullet energy from the muzzle out to 500 yards.
From the muzzle, the 300 Win Mag rounds have an average bullet energy of 3,600ft.lb while the 308 Win has an average bullet energy of 2,720ft.lb. This is a very large difference between the two cartridges, and unlike other categories, there is no overlap between any of the rounds from the two cartridges and this difference continues through the 500-yard mark.
All of the .300 Win Mag rounds but one have well over 1500ft.lb of force at the 500-yard mark. This is extraordinary power for a hunting rifle. The .308 rounds still all carry 1,000ft.lb or a little less at the 500 mark as well, which is still impressive.
Penetration is another factor to a cartridge’s, or more specifically, a bullet’s ability to take down a target. Penetration is especially important when hunting for game with tough and thick bone and tissue where a shallow wound is not going to bring it down. The best way to measure penetration quantitatively is with ballistic gels, but those do not always mimic a bull elk’s tissues and vitals.
The way we will measure penetration quantitatively is by looking at the sectional density of the rounds we have selected for each cartridge. As with other categories, our results for the cartridge comparison rely heavily on the rounds we have selected, but our range of bullet types and weights should even everything out.
The sectional density is derived from a calculation that is the bullet’s weight divided by its diameter and then squared. In theory, the higher the sectional density, the greater the penetration of the bullet as more force is applied to a smaller area of the target. As an example, let’s take two rounds, both with a .30-inch diameter bullet (30 cal). The first round has a bullet weight of 100gr while the second round weighs 150gr. The surface area of the penetration is the same but the second round should have more penetration because of the increased mass.
Depending on the use of the cartridge, you might want more penetration or you might not. How the bullet expands or fragments also changes the penetration, but is left out of this comparison for simplicity and because it doesn’t provide any insights into a comparison between cartridges such as the 300 Win Mag versus .308.
So. Let’s take a look at our ten selected rounds and see how the sectional densities (SDs) compare (Graph 9).
There is not a huge difference in the SDs of these two cartridges which makes sense given they both are the same diameter. The .300 Win Mag does have rounds with slightly higher SDs because of the heavier bullets. What this means for penetration is that both offer great penetration potential given their SDs and velocities. If you need deep penetration, the heavier .300 Win Mag bullets are going to be the best choice.
There is not a number we can put with accuracy for comparison. We could measure groupings of shots at various yards, but that still is affected by who is doing the shooting more than anything else and that same data can vary from day to day depending on environmental conditions as well.
Still, with some of the information, we have already discussed, we can make some assumptions about the accuracy of these cartridges.
The .300 Win Mag rounds that we have used in our comparisons show slightly better muzzle velocities, some rounds more pronounced than others, and they also show a much flatter trajectory than the .308, especially once they have moved past the 300-yard mark. The .300 Win Mag rounds also have slightly better BCs than the .308 rounds. All of this points to the .300 Win Mag being slightly easier to put on target, especially at long ranges than the .308. For shots taken within 300 yards, we think experience with the cartridge has more to do with accuracy than the ballistic performance of either cartridge given there are less than two inches between the averages of these cartridges at these ranges.
Another important factor in accuracy that is often neglected is the recoil. While both of these cartridges have a considerable amount of kick, the .300 Win Mag has several more ft.lb of force than the .308. It’s enough recoil that even more, experienced shooters might have issues holding the shot when thinking about the kick they are about to endure. More so than a single shot is any potential follow shots after such recoil is going to be extremely difficult to put back on target with the .300 Win Mag.
In the end, a lot of it is going to depend on the confidence of the shooter with the cartridge, more so than any numbers we can put in front of you and discuss.

Both of these cartridges are popular enough that they are easy to obtain and are going to be available in various rounds at any major retailer or through online sales. You might find a few more options for the .308 at retail stores, but it also depends on what area you are in. More specifically, the type of game that is hunted there.
As far as price goes, the .308 is going to be a much cheaper round than the .300 Win Mag. Now, if you want the terminal performance of the .300 Win Mag, you’re just going to have to put out a few more bills. We have listed retail prices for these rounds, but be aware that these prices are subject to change based on availability and demand. And if you want to save a few cents per round, handloading your ammunition is an art and a route that a lot of heavy shooters go to save a few dollars in the long run.
Both cartridges are excellent for use on medium to large sized game. For the largest game, the heavier bullet weights of the .300 Win Mag are going to give you slightly better penetration than the .308. The bullet energy of the .300 Win Mag is far more than the .308, especially as the distance increases to 400+ yards. If you’re hunting larger game with shots coming at these increased distances, we would lean towards the 300 Win Mag though that is not to say that the .308 Win would not be able to get the job done. As we have mentioned before, shot placement is equally important when hunting. When taking shots within the 200-yard mark, both of these cartridges perform extraordinarily well at close ranges, and they also do well in use around heavy brush and timber.
While both the .308 and .300 Win Mag have excellent stopping power, the trajectory of the bullets may sway you one way or the other depending on the distance of shots you think you will be taking. Even though the .300 Win Mag has heavier bullets, the increased powder loads the casings can hold provides a flatter trajectory than the lighter weight .308 rounds and make long-range shots for large game more achievable. For hunters, this might influence your decision on which cartridge to turn to but remember that at 300 yards, the differences were not too unseemly and the majority of hunting shots come around or within this range.
For range and competition shooters, the trajectory and ballistic coefficients are going to be one of the deciding factors. Along with the flatter trajectory, the .300 Win Mag rounds will normally have a higher ballistic coefficient making them more resistant to drag and drift. The high BCs along with the much flatter shooting 300 Win Mag at 500+ yards is probably going to be sought after for range and competition shooters. You also have to take recoil into account. The 300 Win Mag on average had several more ft.lbs of recoil energy. While you will have support on the range to handle the recoil, fatigue is going to set in quicker with the 300 WM.
So, who should be using these cartridges? While anyone can become accustomed to using these rounds, it’s a good idea to have some experience with hunting rifles and have some sessions at the range before taking them into the field. The reason for this is because of the heavy recoil associated with these cartridges. Both can have recoil energy of over 20ft.lb which can easily influence the shot of an inexperienced shooter.
Before we wrap up the .308 versus 300 Win Mag comparisons, we want to take the ten rounds we have looked at and pick a few of our favorites for certain shooting/hunting scenarios. This is just our opinion and you might or might not find yourself in agreement. Whatever your favorite round is, we are sure there are good arguments for it, and in our experience, the only thing that matters is that you are confident with it and it gets the job done.
Top Hunting Round
The 300 Win Mag Nosler Trophy Grade AccuBond Long Range 190gr round stands out to use from a hunting perspective. For large and even dangerous game this is an excellent round. The Accubond bullet design gives you deep penetration on large game with controlled expansion to provide a lot of damage. Even at 500 yards this round still carries 2,016ft.lbs of energy, so range and stopping power is not an issue even for larger game. It has an incredibly flat trajectory out to 300 yards and is even manageable at the 400-yard range when the adrenaline is pumping with a ballistic coefficient of 0.64. For a large game hunting round, this one has all the characteristics you look for.
For the .308 Win, we like the Nosler Ballistic Tip 165gr. This is another excellent option for medium to larger game with excellent stopping power. The bullet energy is the highest of the selected .308 rounds with 1,300ft.lbs of energy at the 500-yard mark. With proper shot placement, this round still has the energy and the velocity to make a clean kill. Anything within that yard mark is no issue. Though it doesn’t have the flat trajectory or the BC of our 300 WM selection, a 300-yard shot is no problem in the right hands, and 400 yards is even manageable.
Top Range Round
For the .300 Win Mag, the Hornady Superformance SST 180gr stands out to us as an excellent round to bring to the range. This round offers a decent ballistic coefficient though not as high as some of the other, but it is also one of the least expensive 300 WM we have examined. Even so, it offers the highest velocities and the flattest trajectory than any other round with less than 100 inches of bullet drop at 700 yards.
For our top .308 Win range round we like the 168gr Hornady BTHP Match. This round is affordable which is an important consideration when you plan burning through quite a few. This round has a great BC for .308 rounds, and when paired with the velocity and long-range trajectory, you have an excellent round for precision shooting. The bullet drop is more pronounced than the 300 WM, but when compared to other .308 rounds you can easily handle the 80 and 120-inch drop at the 600 and 700-yard mark.
Conclusion – .300 WM vs .308 WIN
There is a reason that these cartridges are two of the more popular large game hunting rounds on the market and we hope that this article has outlined those reasons. Both feature excellent terminal ballistics and when used in the proper scenario, can be highly effective cartridges.
When looking at the 300 Win Mag vs 308, we can’t tell you which is the best as we don’t believe there is a definitive answer. We do hope that this article, as well as some experience in the field with these two cartridges, will convince you that both should be in your arsenal.
