My brother has owned a 30-06 bolt gun for 40 years. He will shoot about 3 rounds each hunting season to "check if it's still on" Then goes hunting. He has never de-coppered the rifle in about 40 years....At the end of deer season on goes the Hoppes #9 and that's it. His rifle seems to shoot good enough.
Me, OTOH, de copper after almost every range session using proper, non-damaging cleaning techniques and specific carbon and copper solvents....
I am beginning to wonder how much are you concerned about copper streaks in a rifle's bore. Especially if you have run some copper solvent through and have removed most of it...do you hafta clean your bore until there is NO evidence of copper at all, no streaks, no green, etc.?
