That's pretty much my question. I read all of this stuff about copper fouling but I have honestly never used a copper remover. Does it make a difference? I can't help but think that whatever burr caused the copper to be scraped off is just going to scrape more copper off with the next shot. I KNOW that the .44 barrel shoots better and with a drastic change in POI once it is powder fouled. Whether this is due to the powder fouling filling space in my .432 bore, I don't know. I do know that it shoots differently when dirty versus say, the first 5-6 shots. Does copper do something like that?
