At what point or shot count do u clean bore. Also do u clean to bare metal with a brush or just soak with a copper remover and run patches. I have been stripping to Bare metal about every 30 to 50 shots with Montana Extreme copper killer, nylon brush, dewey rods, and bore guides. Then running patch of Bore Conditioner. I read an article on 6.5 x 284 where the guy was shooting matches and winning with almost 200 rounds without cleaning, and got thinking I may be over cleaning!
