How To Choose A Scope For A .308 Rifle
- Construction: Any rifle optics that you plan on using for hunting or tactical purposes has to be durable and withstand the normal bumps and bruises that come with the territory. Aircraft grade aluminum is the standard for quality rifle scopes, and you shouldn’t opt for anything less.
Another feature to a good hunting scope, are low profile windage and elevation turrets. Low profile turrets tend not to get snagged in brush or get knocked off as easily. You still want to be able to manipulate them easily. Regarding tactical, a higher profile might be more beneficial as they are much easier to reach out and adjust quickly and when on the move.
If you’re taking a scope out in the field, you want it to be water and fog proof. There are few situations as frustrating as raising your firearm to see nothing but fog.
- Holding your Zero: While the .308 caliber does not have the most devastating recoil, it still has a nice kick, especially if you are using a high powder, heavy grain load. Because of this, you need a scope that can withstand the shock of recoil while maintaining its zero.
- Fixed or Variable Power: We can place scopes into two broad categories; fixed and variable powered scopes. Fixed scopes have one magnification settings while variable powered scopes can be adjusted across a range of magnification settings.
Your choice between fixed or variable power is all going to depend on the type of shots you think you will be taking. As we have mentioned, the .308 is a versatile caliber that is used in a multitude of shooting scenarios.
A fixed scope might be the choice for you if you are planning on using your rifle for hunting applications in dense vegetation, where most of your shots will be taken at 150 yards and less. A 2.5X through 5X fixed scope will do the trick. Fixed scopes are more durable and less expensive and are the reason you would opt for a fixed scope in this scenario rather than a variable with lower magnification ranges.
The .308 is more than able to reach out several hundred yards and still maintain the knockdown power. A great all around variable scope is 3-9X, but if you are thinking long range, sniping scenarios there are high magnification variable scopes available as well.
When purchasing a variable scope, you need to focus on the lowest magnification setting. While being able to tap targets at 500+ yards is great what happens when it steps out at 70 yards? Will your scope have a low enough magnification with a wide enough field of view to pick it up quickly? It’s an important and often overlooked component to picking out a variable scope.
- Generous Eye Relief: We briefly touched on the recoil produced by a .308 caliber, and you are going to want a scope that will give you 3 or more inches of eye relief. This is more than enough distance between your eye and the rim of the ocular lens.
