Remember that bore snake I pulled between relays?

I think that a clean barrel is very important for good shooting. Everyone probably has their favorite cleaning solvent and that is okay. Borden built the .308 and he highly recommended Boretech. There are so many different ones on my cleaning bench that if they were to get mixed up there might be an explosion of some sort. I do clean the rifle that I shoot at a match within a day or so after the match. I would be interested to know if others have found it better to clean quicker than that. I guess what I am asking is does carbon or copper get harder to remove over time. I actually have a video on that page of a method that I was doing using an automotive carbon cleaner. Seemed to really loosen things up but was kinda time consuming. Using a borescope will always open your eyes as to what you might be missing. A fellow told me not long ago that whenever his buddies come complaining that their rifle just want shoot the first thing that he asked is “Is your barrel clean?” He then proceeds to show them that it is not, much to their surprise. And always remember that Champion Sniper reminds you ^ to “keep them clean” WWE

Careful with the nylon and drill. Nylon will pick up trash and it will score the rifling/throat.

I actually use boretech and Thorro clean. I’ll stick a brass brush size larger than the bore in the neck and twist it a few times to keep carbon ring out. It also helps to have the reamer on hand… you can just put it in the chamber and spin it by hand to remove a carbon ring.

Carbon gets harder to remove. It doesn’t go out into solution as readily as copper with a chemical reaction.

I would suggest thorro clean (recommends a nylon brush) as well, Tyler and I used some on an old dasher barrel I had and the results are pretty crazy and the best part is it doesn’t take long. I wouldn’t be scared to use kroil, boretech, jb, etc with a brass brush either.
