[QUOTE="Fiftydriver, post: 76699, member: 10"] Roy, A simple answer to your question, "Is a bullet fully stabilized if its making round bullet holes?" is NO. THere can be significant yaw in a bullet even with a round bullet hole. IT does tell us that we are at least very close to stabilization by getting consistant round bullet holes. The hardest test for a bullet in my opinion is in very cold temps at high altitudes. Also, terminally, a bullet on the fringes of stability will generally tumble after impact whereas a bullet that is fully stabilized or rotating more then required will often penetrate straighter. Now there are more variable to this obviously so take this as a simple comment that a fully stabilized bullet will penetrate straighter then a marginally stabiled bullet. With an expanding bullet this is less dramatic but in tests with the big bore rifles firing solids, this has been proven true. Basically the best teller of bullet stability is to test at extended ranges and see what the groups look like. Marginally unstable bullets will result in larger groups the a properly stabilized bullet. Kirby Allen(50) [/QUOTE]
