Rust in my bore!

[natedog]

Forgive me, rifle gods, for I have sinned.

I've been shooting Korean corrosive ammo in my M-1, and have cleaned with a Windex soaked boresnake. So far, I've had no problems, but I took a closer look today and found that the last 2" of bore have some flecks of rust in the valleys between the rifling. I've put a heavily Windex soaked boresnake through, white patches, then a few solvent soaked patches. The patches still come out with some fouling, but no more flecks of rust- but, using a bore light, I can still see some rust near the muzzle. Help!

You know, under closer examintion, the streaks look more gold or yellow than red. Could this be copper or some other type of fouling?

Most likely copper fouling.

Pick up a bottle of Butch's Bore Shine, run a heavily soaked patch down the barrel and let it fester overnight.

Punch the bore with a clean patch and run a few more patches soaked with BBS through it. Dry patch, etc.

IF there's still enough copper fouling that's offends you, let it fester once again.

I would like to suggest some Outers, Gunslick, or Wipe out foaming bore cleaner. I fill the barrel with foam, wait a couple hours, then push the copper soaked patch out. It works better for me than anything I have ever tried. I get mine at Wal Mart, about 7 bucks per can.

whipe-out worked real good on some lead fouling I had, but I really like the Montanan-extreem bore cleaner, run one wet patch through and the green ooze out. As how to get the hard stuff out if you don't want to use harsh chemicles, get a .30 cal nylon brush and scrub it some.

FWIW, the field manual (which was written assuming corrosive ammo would be fired) says to patch the bore each day for 3 days after firing.

It's probably copper fouling..

I run a super wet patch through it, let it hang muzzle down standing straight up, and wait about 10 minutes. Then run a few patches though it, the stuff that comes out is disgusting..

Copper fouling

Sweet's 7.62 has worked for me in removing copper fouling. Wet a patch, not a tight patch, run through bore to anoint, wait 5 or 10 min, run a brush through--a nylon or stainless steel brush won't care about the copper solvent--then run patches through until they come out clean. Inspect. Repeat if necessary.

I have a brush which is actually a spiral of a spiral of stainless steel wire. I try not to use it often, but when there is something in there that really shouldn't be, and it laughs at everything else, that's what I use. IIRC, it is called a Turner Tornado. Can't recall where I got it. Works good on lead fouling in my revolver, as well as copper.

Do the instructions really say "fester."
