Copper fouling

[KorbenDallas]

Hey guys just wanted to make sure this is copper fouling and nothing more serious. I just noticed today on a barrel that I assumed I cleaned well. This is an xds 3.3 9mm and I've only used mpro7 cleaner, mpro7 oil, and brass brush to clean bore. Any ideas? Also about 500 rounds through firearm.

Got accuracy problem? Of not, it's fine.

Best thing for removing copper: http://www.amazon.com/WIPE-OUT-5OZ-BORE-CLEANER/dp/B00162NQ0W/ref=sr_1_1?ie=UTF8&qid=1411412621&sr=8-1&keywords=wipeout+gun+cleaner

No accuracy problems except for the ones that are user controlled. Just wanted to be sure it was just fouling and not damaged.

I will look into that for my next cleaning.

About all of my rifle barrels look like that. You can get it all, but it's a pain.

Are you using the regular M-Pro 7 or also their copper remover?

I use both on my .204 Ruger, and find it very effective. I foul the bbl pretty badly on that one.

You need to shoot powder coated cast boolits. :cool:

Yep. Generally more trouble than it's worth, and it's possible to do more harm than good.  Some barrels even shoot a little better with some fouling.  It fills in the imperfections.

I have used only the cleaner but I will try the copper remover next.

Oh magical wizard can you make me some special boolits? :)

Alright well I'm pretty sure its rust or some type of chemical etching unfortunately. Got the copper remover and it looks better but there are a few spots that will not go away. This is my carry weapon and maybe I let it go too long without re-lubing. I also left it dirty after firing five rounds because I hit the range again a week later and thought it wouldn't hurt it. I guess I put too much faith in the "glock" like finish. 500 clams and six month of use and I have a rusted barrel. Although it's my fault I'm still disappointed.

[peejman]

Nah, it's copper.  The bullets would blow any surface rust out of it.  Don't worry about it.  You'll do more harm than good trying to get that last little bit out of it.

Rarely do I clean my barrels unless accuracy becomes an issue.  I do clean the chamber.  At most I tend to pull a bore snake through it once in a while.

brass brush to clean bore

Try a nylon or synthetic brush. Brass brushes can leave what appears to be copper fouling when combined with some solvents.
My 9mm XDM 5.25 looked like this before switching to a nylon bore brush. The solvent I was using at the time was Hoppes #9. Now I use the nylon brush and have started reloading with CFE pistol powder and the fouling has disappeared.

I will try that out after next range visit. I've ran enough rods through her the past few days she needs a break... lol

I guess I will use the brush it comes with since it nylon. But if you seen this in person I'd say it not going away, it's on the lands and grooves.

Well I would, but I do not shoot 9mm, so no mold. :surrender:

All good RED, but it does make me feel like I'm shooting a weenie caliber :(
And I do admit that large xds 45 barrel looks a lot better than the 9mm but 45 ammo is so expensive.

At < $7 for 50 rounds with plated bullets, I wonder how I ever afforded to shoot without reloading. Imagine how cheap these guys that cast their own are coming out. Makes me wonder how I can afford not to cast my own, LOL. Edited September 24, 2014 by BigK

Fwiw Italian gun grease has a product called copper eliminator that works well on copper build up. It's cheap n it works.
