OK, in a different post, i found out (the hard way) that cleaning solvents go bad with age. anyway, after removing what must be at least 10 years of copper fouling, how can i tell if i have screwed up the barrel? other than, of course, just shooting it and seeing how tight of groups it still holds. also, when i am doing that, (grouping) should i use hand loads with ultra tight quality control, or just use some otc regular shells? my guess is that hand loads would be better, IF i had some already worked up and known to be an excellent accuracy round (which i do not). it's a .300 win mag. in a remington 700. idea's? thanks.
