Discolor/damage muzzle brake with solvent?

[Djstorm100]

Typically I just turn the rifle with muzzle down in a vise, so that the rifle is vertical. I then will put a small cup filled with hoppes and let it set over night. I didn't have any hoppes so I ran butch bore shine.

I pulled my rifle out of the safe tonight, it's been 2 months since I cleaned the muzzle and I guess I didn't wipe off all the carbon/solvent because in the corners of the brakes weregummed up. Clean it up, no problem. I did notice the top and bottom sides, inside the brake turned red/green. Thinking this is just a reaction from Butch Bore shine. Has this happen to anyone else?

There's no damage or concern about the bore. Just curious of what type of reaction caused this (why). What's ever left will be blasted out when I go to season the barrel.

I would never "Leave" cleaner in my rifle, overnight. That stuff eats metal, copper is a metal, once the copper is gone, stainless steel is a great next meal.

This goes back to Gale McMillan saying most barrels are ruined due to over cleaning vs shooting. These cleaners kill barrels when over used.

That said, it's just the carbon oxidizing turning green, it wipes right off. The red I have not seen, probably a result of the cleaner.

Wipe them down, punch the bore before putting them up, but don't leave stuff in there, overnight or otherwise.

The rifle / barrels do not get "That dirty" where you need to leave this stuff in there. Bad practice.

Thanks Frank.

Only the muzzle is left in the hoppes over night. Nothing ever stays in the bore. The carbon started to build up from shooting with my ultra 7. I'm thinking the red is from the cleaner on account I used butch bore shine this go round. I did bore scope the barrel last night and it's fine, in that regard. Only patch it ever 300-400 rounds. Will run 2-4 patches of hoppes/dry if the match is kicking up a lot of dust/dirt.
