I recently got "Caught" by my uncle cleaning my rifle without using a copper removal solution on one of my rifles and got a speech on how not removing the copper fouling every time I shoot one of my guns will ruin accuracy. My general cleaning procedure is a good scrub of the moving parts with Breakfree CLP, 20min soak of CLP in the bore with patches run through till they're clean, and Shooters Choice FP-10 for lube where needed. Is there validity to the argument that copper removal is super crucial every time I clean a gun? Correct me if I'm wrong but if the copper builds up enough will the next bullet that goes through the bore not either polish it down into the bore or take it out the end of the barrel itself? Looking for some insight here.
