View Full Version : What is this crap in my barrel?

This is HXP 1980 fired from my m1. I left it for a week an discovered this stuff. Is it salt?

That's copper residue from the bullet jackets

Rinse very well with hot water after you shoot surplus ammo.

Also possible that your ammo is corrosive. Hot water down the bore and then clean like normal.

Had the same stuff in my muzzle brake after shooting some steel cased .223. Cleans right out tho.
I don't know what it is but that HXP is pretty filthy even though its supposed to be non corrosive.

Yep, I believe thats oxidized copper.

Looks like copper to me also. I cleaned that color residue from a buddys rifle, that he failed to clean well, after a few weeks.

Its like copper rust (oxidation). It should clean right out. I get it on my muzzle breaks/flash hiders often.
