I'm done with casting lead bullets , done way too much , I buy bullets for my 303 from dodgyrog sized exactly to my bore , my bore is 313" and in good condition so I buy .314 bullets . Don't shoot lead bullets after jacketed without de-coppering the bore scrupulously , if you fail to do this any groups you achieve will be of the shotgun variety.

I use Boretech Cu+2

Hopps No.9 will do it ,just follow the instructions carefully.

Quickest is clean shot with the accelerator but long term if you can store the rifle horizontal is C2R
I also like k12 too
Patch bore first with brake cleaner to remove carbon

would ammonia be good too ?
