i have been working with a 6mm rem varminter lately and im not satified with the accuracy so far. im think a new barrel is in order... if you were to pick a new barrel whose would it be and why. i have had a few shiliens and was please but they dont seem to last long. i see that they offer a few differant rifling types, and claim better barrel life and slower erosion. < 3 grove, r rifling, canted rifling.. this is all good but what are the real world results and who is producing the fewest duds out there? any thoughts welcome...
