Re: Cleaning question
You can still break in your barrel. Clean it till there is nothing left in the barrel. (I use sweets and JB) Than do a break in like it was a new barrel. If you do not break in your barrel the the first few rounds fill the rough spots with copper and they never get smooth. I did a break in on a old hand me down 303 brit. with many rounds through the tube. After days of cleaning to the bare metal I did the shoot 1 and clean thing. The gun now cleans 10 times easier and groups about half what it use to.
