NEVER use a steel brush, it ruins a barrel right off with scratches, even if not readily visible,. Bronze or nylon only! Thanks for watching.

Copper and carbon overlap each batch and forth. If it is a stainless steel barrel I will use CLR with 3 patches and then flush it out with isopropyl alcohol (IPA) and then attack the copper. I’ll then use Patch Out with Accelerator to go after the copper. I may have to go back and forth attacking carbon and copper which is why you need a borescope. No reason not to have one nowadays as Teslong borescopes are affordable and great. Then, I’ll use KG-2 bore paste, 10 strokes on a patch to get rid of the really hard carbon near the throat, flush with IPA, and check with a bore scope to ensure it is clean. Lastly, wet patch with Lock-eze (colloidal graphite) and dry patch a few minutes later. You really need to use a bore scope to ensure your barrel is actually clean. Several times I’ve put a borescope down a barrel after it was ‘cleaned’ and it was very much not cleaned and striped to bare metal.

Do you find it necessary to completely remove all the copper with each cleaning? I have a rifle or 2 that seem like they shoot better if the barrel is somewhat fouled with copper.

I used to be a clean freak, now I do very little if at all... I find no appreciable discrepancy in accuracy, only watch for rust. A city dweller with nothing in terms of a shop to work in, it was always a big deal to do the kind of maintenance you're talking about. At one point I feel I was spending more on maintenance than I was enjoying actually shooting. I've heard many views on cleaning, even zero cleaning, aside from if you're actually using the weapon as a shovel, I feel it's unnecessary. If the action and function of the weapon isn't inhibited, most crud will be blown out with subsequent shots. There's too damned many variables in the performance of a firearm to worry about so many incidentals... and I don't... and I shoot quite well and happily, thanks! 😊👍
