[QUOTE="RockyMtnMT, post: 1597572, member: 7999"] Thanks for the response. The more we test the more it seems like pre copper bullets need more stability than what the Miller formula says. Particularly when the bullets get long for caliber. Our only conclusion is density of material. Then comes the dynamic stability that there is no practical way to determine. By the way our bullets are lathe turned pure copper. No cup and core bullets here. [/QUOTE]
