[QUOTE="65WSM, post: 648539, member: 9551"] First we need to know the length of the Berger 170 gr bullets to use a formula to figure out the stability of the bullet. The Greenhill formula is the best known but RSI says they have a nore accurate one. Second, what kind of powder are you using and what charge. It sounds like you have a real impressive load. Remember that 140 Accubonds have a higher BC than the Bergers. For 170gr bullets I would expect that VV N-570 would be your highest velocity powder. [/QUOTE]
