I have a Cooper in the 6.5 PRC that someone wants more than I do. I am going to regret this, as it will shoot 124 HH in the .2's. I do not want to be without a 6.5 PRC and I was looking at the Proof Research Tundra, and G. A. Precision rifles. Both of those firms are twisting their barrels at 1:7.5 twist vice Coopers 1:8 twist. What is this giving me that the 1 in 8 twist doesn't?
I know this should go down in the reloader forum, but I figure most reading here are reloaders and can tell me if the 1:7/5 will stabilize the 124 Hammer Hunter bullet.
