[QUOTE="SBruce, post: 614542, member: 21068"] Curious what's your elevation? Apparently (according to the miller formula on JBM's website) a 9 1/8 twist shooting the 105 A-Max at 2900'/sec at my altitude (4100', pressure of 25.5) will not ideally stabilize that bullet below 56 degrees temp. According to the program; when velocity, elevation or temp drops, the stability factor goes down too. At my altitude, I didn't have any problems shooting the 105 through a 9 twist, but it was at 3100'/sec and above 56 degrees too. [/QUOTE]
