[QUOTE="quigley257, post: 1773118, member: 84442"] So far, my brothers rifle with 1/8 twist has handled up to the 88gr ELD-Ms beautifully, but they are only 1.240" long(still long for .224" bullet). I built mine first and knew that I wanted to shoot the 95gr MatchKings so I went with the 1/7 twist on my rifle. The length on the 95s is 1.310" which is very long for a .224" bullet. Using Bergers twist calculator, a 1/7 at 3125fps yields an SG of 1.52 with the 95 SMK. A 1/8 twist only gets an SG of 1.16 with the same bullet which was a no-go in my book. Better to have a bit more twist to get into the comfortably stable region. [/QUOTE]
