[QUOTE="300spanker, post: 417409, member: 12221"] I have been shooting 3 different 300 ultra's with different twist rates. 1in11, 1in10 and 1in9, and it seems that the faster twist gun is producing a better BC at 1000 yards. I am shooting 210 bergers at 3200 fps out of each gun. Is this possible. The 1in11 bc is around .630 the 1in10 .665 and 1in9 around .700. Is there any theory around this to support my situation, can a bullet stay off the ground a little better if spinning faster???. thanksgun) [/QUOTE]
