[QUOTE="TopPin, post: 2760899, member: 109070"] Side note run an 8 twist in a 260 AI, the 7.5 twist does not seem to produce the same velocity numbers as an 8. 7.5 twist so far has produced slower velocity with same bullet weights as an 8. With same leangth barrels (22 and 24in leangth) I’ve scratched my head on this for awhile, but it really does make a difference. [/QUOTE]
