[QUOTE="DJ Fergus, post: 1745252, member: 93895"] I know that at one point or the other, 230 & 215 Berger's , 225 eld, stated minimum twist of 10 but my thoughts are 9 twist would be optimum for those at my elevation, 700ft. Ive run lots of numbers through jbm stability calculator for my rifles & bullets I shoot or might want to shoot. For my rifles, if I can stay with in a stability factor of 1.7-1.8 and not get much over a factor of 2, those are my rifles that are the least finicky. I'm not saying other combinations I have won't shoot well but those just happen to be the most fault tolerant for me. Possibly just coincidence but I don't think so. I have nothing to base this on other than my observations, some one else may have totally different results. [/QUOTE]
