I apologize if this has been done to death, but I am considering a new barrel to replace my E.R. Shaw .308 on my custom Stevens 200. I am considering a 20" .243, .260 or 6.5 Creedmoor. I'm wondering which barrel maker makes the best prefit. I have looked at Sin Arms, Shilen, Criterion, Mcgowen, etc. any suggestions? Thanks guys!
