[QUOTE="Buttermilk, post: 2084022, member: 5262"] I’ve got a 17.5” bbl with a 1:9” twist in my 7mm RSAUM. If I were to do another it would likely have a faster twist. I’d probably do something in the 8.5” range even if I only shot 162-168 gr bullets. If I were to shoot 175-195, I would go faster. The Berger stability calculator will help you decide a good twist rate. I get 2830 to 2850 fps with 162-168 gr bullets from my 17.5” barrel. [/QUOTE]
