Things to Consider Before Buying the Best Rifle Scope for .308
You can’t just buy any scope willy-nilly and expect stellar performance.
If you want the BEST long-range scope for your .308 rifle, here are the things you need to consider:
#1 Magnification Settings
Let’s start with the close and mid-ranges:
Close to Medium-Distance Shooting
If you will only be using your rifle for shooting about 250 yards (medium-range shot), you want at least 6 to 9x in magnification settings.
For target shooting, you will want a 24x and higher magnification range.
But if it’s for tactical shooting, get one with a lower variable magnification range.
Meanwhile, for a long-range shot (350 yards and up), you will want a scope with a high magnification power.
Get something that can handle about 10x or higher magnification if you will be hunting with smaller targets.
#2 Lens Coating
You want your lenses to absorb as much light as possible to get maximum clarity, but WITHOUT the glare and reflection.
This is where lens coating will help you. A single lens coating will reduce the reflected light, which then reduces glare.
The more coatings your lens has, the better for glare reduction.
Lens coating options range from single coating, fully coated, multi-coated, and fully multi-coated. Let’s look at their differences:
- Single Coating – This means that one of the lenses has at least 1 layer of coating.
- Fully Coated – When it says the lenses are fully coated, it means that ALL lenses have at least 1 layer of coating.
- Multi-Coated – This means that at least 1 of the lenses has more than one layer of anti-reflective and anti-glare coating.
- Fully Multi-Coated – And lastly, this means that more than one lens has more than one layer of coating.
What’s your shooting style? Get a reticle that matches that!
When choosing your reticle, no particular one is better than the others, so just go with the one you like.
Most people prefer bigger lenses because the bigger your objective lens is, the more light it can capture— meaning a clearer sight picture for you.
Although, do keep in mind that the bigger the lens, the heavier it will also be.
#4 Parallax Adjustment
For long-range shots, the reticle will not always be in the same focal plane as the target, resulting in parallax.
When this happens, your eyes move with respect to the sight. The reticle will wander about over your target.
Parallax is something that you will always have to deal with on long-range targets, so make sure to get one with a parallax adjustment.
But if you’re more on short to medium-range shooting, you won’t be needing a parallax adjustment.
Now that you know what to look for when it comes to buying your own scope, it’s easier to find which one suits you!
Frequently Asked Questions
How Far Can a .308 Shoot?
Typically 1000 yards.
But it depends on a lot of things, from the skill of the shooter to the load and barrel length, the angle from which you are shooting from, and many more.
What Is the Ideal Range for a .308?
Again, this depends on a lot of factors.
For deer hunting, a safe answer would be around 300 yards.
How Much Eye Relief Do I Need for a .308?
You will want to have about 3 to 4 inches of eye relief if you’re only using one eye.
But if you want to use a scope that allows you to keep both eyes open, you might want more eye relief than that.
What Scope Size Should I Get for the AR .308?
Whatever you want.
No, really. When it comes to scope size, it doesn’t really matter what size you get because there isn’t an ideal size that will perform better than others.
Simply get one that you prefer and suits your needs, and make sure it will fit in our rifle well.
What Is the Effective Range of a 308?
The ideal range is around 300 meters, but the overall effective range would be around 800 meters.
That’s a safe bet that you can hit your targets when the weather conditions are not optimal.
How Far Can a .308 Shoot Accurately?
It actually depends on the size of your target.
For instance, a deer and any other similar-sized target would be at 300 yards. A prairie dog will be at a mile.
What Is a .308 Good For?
The 308 is best for deer, pronghorn, elk, moose, and bear hunting.
What Magnification Do Military Snipers Use?
Usually, it’s at the 2x-12x magnification level.
That’s ideal for long-range shooting, so you can start with that setting and just rest it at a higher or lower magnification.
Why Do Snipers Wrap Their Rifles?
It’s really just for camouflage.
Wrapping the rifle creates little sleeves for it and helps it blend into its environment better. You could also try doing this to hide from targets with sharp vision.
How Many Screws Do I Need for Scope Rings With .308 Winchester?
4 holes to 6 holes rings are usually recommended.
But it mostly relies on the material used to make the rings and the height at which the scope will be installed.
So if you’re dealing with steel rings, 2 to 4 screws will be enough, while aluminum rings will need 4 to 6 screws.
