Re: 8 or 9 twist for 7 STW using 180 Berger?
As Lefty said, I have been having excellent luck with my factory Sendero SF 9.25" twist barrel.
My A-Bolt II 7mag has a 9.5" twist and it shoots them ok, but it prefers the 168 VLD's.
My .280 AI build will have a 1:9 twist.
I have come to realize that a 1:9 is the most universal 7mm twist for shooting 160-190 bullets. I'm sure it would stabilize 140's just fine, too.
