The eternally dirty Mosin?

[deimos256]

On my mosin and mauser i used Hoppes bench rest, or whatever their copper solvent is called. I ran a wet then dry patch through until they were relatively clean, then ran a wet patch through and let it soak overnight then went back and did the wet/dry patch routine and eventually they started coming out clean. I havent been to the range yet to see if it improved accuracy but knowing the bores are clean is good enough for me.

Sweets 762

FC has it right. I use Sweets 762 copper solvent and it cleans a lot more out than Hoppe's can do. I use Hoppe's to get most of the powder out, then I swab the barrel with the Sweets; let it soak for 8-10 minutes then scrub with a brush; patch it all out with 5-6 patches. Works great.

Patches soaked in hot water to get the corrosive salts out (corrosive primers produce potassium chloride when fired - close to table salt). Once the wet patches come out clean(ish), a few dry patches and then follow up with Hoppes/Hoppes Benchrest untill I get bored with the varying colors of blue/green that they come out.

I have never gotten a Mosin bore *fully* clean like I can with the guns I have bought new. I can always leave the copper solvent to soak for 5-10, or run the brush up and down a dozen times and get patches out that look just as bad as the ones I pulled out an hour ago. I kinda figure that I probably do more cleaning per round than the original owners did, so if I just keep shooting it, eventually it will come clean?

While I don't disagree that cleaning a Mosin with boiling water or some other water based cleaner works, I will say that it's not the only way to clean one and prevent damage....I bought my first Mosin in 1989 and have shoot piles of corrosive ammo thru it. I never once cleaned it with water. I just cleaned it the day I shot it with whatever brand bore cleaner I had on hand. The bore in mine is just as shiny as when I bought it.

Green patches? Yeah, it's copper. Hoppe's #9 doesn't do much for copper. Try Hoppe's Benchrest and follow the directions. It will do a good job removing the copper.....My guess is that is basically regular Hoppe's #9 with some ammonia in it.

This is pretty much my deal too, but a couple of my Mosin's will bleed green a couple of weeks after it was last shot. I just figure that they had years of copper thrown out of them without getting properly cleaned.

How does one go about cleaning their bore with hot tap water?

Do you just take the entire rifle and let it soak in a tub or hot water? Do you remove the stock and place the receiver and barrel in the tub? Do you somehow just run hot water into the breach using a hose or something?

I just ordered a 1891/30 so enquiring minds want to know.

I have a 1917 that was used as a ceremony rifle firing blanks through it. I tried everything and still the patches came out dirty. Then I tried about 5 passes with JB Bore Paste. Looks like a mirror now. Just my opinion...

You can do either or you can just run a few patches wet with powder solvent through the bore..

Take the rifle out back and pour boiling water down either end of the barrell. I do it from both ends since the chamber and receiver need cleaning also. You won't hurt the wood unless you've refinished it to a high CZ shine. Remember where these old war horses started their lives. Out there in the dirt, rain and mud of the battlefield. That gunsafe you store it in is the Hilton to them. Hot water ain't gonna hurt a thing.

Boiling hot water is best, its self drying, almost insatnt when its very hot.
I have a small funnel I use to get the water to the chamber without getting everything wet.

Like it was described, step outside, pour, scrub, rinse, dry patch and oil.....yer done.

You sure about that? Also, wouldn't you need to intensively dry the rifle after running hot water through it to prevent rust?

When shooting corrosive milsurp ammo, just clean the weapon like one would a blackpowder firearm with soapy hot water, or plain cold water will work in a pinch.

Yep, I'm sure. See post #35.
