[QUOTE="Fitch, post: 481796, member: 19372"] I think 1:9.35 will be about perfect with the copper bullets. They are physically larger (longer) for the same weight than lead core bullets and thus need a faster twist than lead core bullets of the same weight. The longer Cu bullets can rob you of power capacity. Since you are setting the gun up for Cu bullets from the start, you might want to think hard about what you can do to integrate magazine length and chamber throat to get the most powder in the brass.
