Guns that do anything pretty good and few things great are heavenly!
When I was working up a load for my Seekins Havak I was getting over 1 moa. Seekins told me I could send it in, even they get a bad barrel occasionally. I ended up finding the loads it liked and never had to send it in.New barrel. Happens sometimes. My first bad barrel experience.
My brother in law bought a brand new Rem Sendero in 300 RUM. It was a 12" gun at 100 yards. They rebarreled it and she shoots sweet now.
