I have heard shooters claim to never BRUSH a barrel.
I would hate to think what that barrel looks like.
The shooter who thinks he has a perfectly clean barrel because
he gets white patches, probably doesn't own a bore scope.
The miracle cleaner that will remove carbon w/o a brush
hasn't been invented yet. Just MHO. LDS
I won't say "never", but I don't use a brush much. I generally clean after 25 rds, and try to start just after a 5-round string. Boretech C4, several wet patches, single pass until the carbon lessens, then short stroke to sort of scrub; followed by either Boretech copper remover or KG-12 on patches to get the copper.
Borescoping shows it gets, at the very least, pretty damn clean.
The carbon ring at the front at the chamber is dealt with separately if needed (doesn't seem to show up all that often; at least not to any great degree.)
And to the original post, I use 1-3/8" patches from Brownells on a 6mm Boretech aluminum jag.
Seems to work for me.
