[QUOTE="Canadian Bushman, post: 2091942, member: 41122"] More than likely no. You may get slightly larger groups than you may of with a slower twist but this is arguable, and depends on bullets balance and bullet/case straightness. You will also have to deal with a bit more spin drift. Ballistic calculator will do this. On the plus side, higher stability has been shown to aid in the performance of bullets traveling back down to subsonic speeds. If i shot a rum i would definitely shoot an 8 twist despite these very minor issues. With that amount of powder i would want to be able to shoot the 230, 240, and 250 class 30’s. [/QUOTE]
