Pitting

Uploaded on January 18, 2009

I was recently scrubbing the copper fouling out of my Remington 700 and noticed some pitting in the barrel? How much will this pitting affect accuracy? Would running some of those Tubbs abrasive bore finish bullets help to restore accuracy by smoothing down the rough spots? What is the best non-abrasive copper remover?

Google the terms "fire" "lapping" and "barrel" to get some idea of the controversy surrounding this topic. I've never done it, but many have posted the results of their experiments online. I can't determine a clear consensus either way, but having a competent gunsmith lap the barrel for you will always be superior. Hoppes Bench Rest 9 is a good copper solvent. Run a wet patch and let her sit barrel down for while. Don't want that stuff running back into the action. Scrub good with a brush and then dry patch. If the patches are coming out blue or or greenish blue, continue using dry patches until they come out reasonably clean, and then run another wet patch. Go back to the dry patches and repeat until you stop getting the blue color. It takes 40 forevers and about a hundred patches, but if there is no more blue, there is no more copper, period.

Thank you Armchair. I will do this to get all the copper out of my barrel. I have tried cleaning the copper out, but didn't know it takes so many patches. Hopefully my barrel's not pitted all to hell.
