[QUOTE="Teri Anne, post: 2771981, member: 118816"] In my case it's simple, I use copper remover when there is copper to remove. I have had a lot of rifles, mostly bought used and have a borescope that I use on a fairly regular basis. To my way of thinking there are two types of copper found in the barrel, first there is a smear, which looks just like that, a copper coloring on the lands and grooves but no real substance to it. I have found smears to be common and do not seem to affect accuracy. On the other hand what I call globs are just that. They fill in the corners of the base of the lands impairing the ability of the rifling to properly grab on to the bullet and severely affects accuracy. Just went through issues like that with a Browning 300WM. It copper fouled so badly that accuracy dropped off after 5 rounds after cleaning. It was necessary to do a copper removal every time it was shot. Bore scopes can be wonderful tools but can also be your worst enemy. I have had barrels that looked like 30 mile of badly graveled highway that shot sub moa all day. Conversely others that look slick and clean that scatter bullets in a shotgun like pattern. If you see a rough area don't worry about it until it causes accuracy issues. [/QUOTE]
