I have been hand loading for a .308 REMINGTON 40 XS 1:12 twist in a 24” .The load I'm using is once fired Lapua brass,168 gr. Sierra Match King Bullets ,42 grains of Vith. n-140 and CCI BR-2 primers, COAL 2800. I don't think the bullet is stabilizing through the air because the hole that it's creating is slightly large, I have gotten 1/2 MOA @ 100 yards with this load. I have tried many hand loads through this gun including 168 gr. Sierra bullets and IMR 4064 powder. Any tips would be greatly appreciated. Thanks!
