[QUOTE="ARlife4me, post: 2494998, member: 105694"] Sierra manual list the 230smk (30cal) requiring an 8 twist or faster. No speed base, just twist unlike the 22cal 90gr at 6.5, but if velocity is above 2,650 a 7 will stabilize. I have some 210 and 240 smk for a 300wm 30" 9 twist. Also using berger 215, 230gr and hornady 225. This is for a new build. I'm 1 recoil lug away from completion. [/QUOTE]
