I have shot thousands of berger 215's out of my 1-11 twist 308W, you might be ok.I have a Hawk Hill barrel I'm gonna spin up on a defiance deviant LA, it's a 28" blank with 1:11 twist I know that's slow for a 300 prc but is there a chance I can stabilize a 212 grain bullet ?
If anyone out there is looking for a 1:11 I would trade for a 1:9
