Re: Lets see some 300 Blk Out bolt guns....
Hi,
Is MOA accuracy achieved in 1-8 Twist 300 BLK when pushed Supersonic ?
When you look at 30BR, people are having to use a 1-17 or 1-18 twist to get best accuracy from a 110 to 120gr 308 head. My understanding of Benchrest Accuracy is they expect 1/4 to 1/3rd MOA accuracy out to 300yards.
If you have a great scope (i cross deck a 5-25 S&B, Double Turn Turret) saving my zero points on a iphone), it is not very satisfying to squeeze off a round in a rifle with little recoil, and see the bullet impact somewhere the cross hairs are not. I like to shoot 2 inch diameter explosive targets, the type meant for sticking under clay pigeons, at 150 to 300 yards. For many rifles, this can be too big an ask, requiring a larger target (guess I should get a 10" steel gong) or a scope that is of a lower magnification that does not lead to such high expectations. Thus, with cast bullets and gas checks, plinking at 50 yards with a high calacity magazine in a Browning 308 BLR lever action, I use open sights or a 2.5 magnification scope.
Gee
