I am no gunsmith but I think something is wrong with the crown on my new savage f/tr308. Today I broke it in and sighted in the scope. When I got home I cleaned it again and looked at the crown for the first time.there was a thin rough metal ring out from the crown like it was never reamed. I only shot 40 rounds threw it and used a brass jeg and brush to clean it. It never really grouped from the get go. Any input?
