mosin nagant bore cleaning
How much is too much? I just cant seem to get the bore clean. Ive been at it for an 1hr and a half now. I scrub with brass brush then patches and hoppes then clean patches and hit it again with brass brush. I seem to get more grime out ever time I use the brush. Any thoughts? Is it just that dirty? Sometimes the patches come out with a green tint...corrosion? The bore is fairly shiny and has good rifling

On these wonderful old Russian rifles you see bores like that all the time. They were shot with corrosive ammo and then put away without proper cleaning. They used ammo with corrosive primers.
There is not much you can do with them. That being said, lots of them have great accuracy even thought their bores are dark. I have six different models of the Mosin Nagant and they all shoot great even with with dark bores.

Ah, yes, I am registered there. I forgot all about that site. I have 5 mosin myself, I seem to favor the carbines and have gotten lucky with them as I bought them from Gb and they all have shiny bores with good rifling. I have shot one, yet, but I have fallen in love with these rifles and plan to buy more. I guess I shouldn't be too upset as they are 60+year old rifles in very good condition. 0 -
Try some JB Bore paste on patches. Blue/green is copper fouling which can come from your brass brush in a pitted bore. Dark bores can shoot ok but I don't think they set any records.
I like Shooter's Choice better but I still have Hoppies.0 -
One way to clean-up a dirty bore is to shoot it a lot, 20-40 rounds or more, then clean it well while the bore is hot. Be careful. The bore will be really hot. You can get burned or start a fire. 0 -
My favorite way to clean a extremely dirty bore:
1. Remove wood
2. Plug end of barrel. I like to use a silicone. Remove all traces of oil first, so RTV or silicone will stick.
3. Place barrel assembly barrel down and using a small funnel, pour in your favorite bore cleaner and allow to sit overnite.
4. Remove silicone plug and catch used bore cleaner & dicard.
Sometimes may have to repeat process but I have cleaned many a milsurp using this method. The spent bore cleaner will usually be green and dark.
After this process, you can brush and patch clean.0 -
This is what I do most off the time. Cleam cosmo off rifle and check headspace. Head to range with ammo. Shoot the rifld about 29 rds and clean again . Most off thd junk comes out. Then I use blackpowder cleaner to get the carbon out. Then fired anothef 20 rds again. Clean with a good clean likd Sweet 7.62 or Butch's.

Agree with spec4, TWalker and chiefr.
Let time and chemistry work for you.
Cleaning a warm gun on the range gets more fouling out and does not stink up the house.
Soaking lets the solvent action work, but be sure to use a solvent that does not specify a time limit.
I use the foam cleaner and let it soak but don't know how well it works on a neglected barrel.0 -
You can also plug bore, fill with KROIL, let stand a day, drain, and brush. Kroil can actually get between carbon or metal fouling and the base metal. 0 -
It's highly unlikely you will EVER get a pure white patch through an old milsurp rifle. Some people do, and I am happy for them. [;)] But, getting white patches isn't all it's cracked up to be. [:D] You didn't get that gun with the end goal of getting clean patches through the bore. [:D] If the rifling looks clean and sharp and the rifle is shooting tight groups. . . . you're done. Enjoy the shooting. [;)] 0 -

Oh yeah. . .it IS that dirty. The gun has been shot with corrosive ammo, the bore allowed to pit and rust, and then the process repeated, probably multiple times.
So you have powder fouling, copper jacket fouling, and barrel rust all piled in layers on top of one another, and wedged into little microscopic crevices caused by barrel pitting/erosion. That's fairly typical of these old restored Mosins. They good great on the outside, but the bores look like rusty sewer pipes.
When this happens, yeah, its real tough getting it all out because you've got the different layers, plus stuff lodged in where its tough for bore bristles (let alone just patches) to scrub.
If you really want this clean, as mentioned, you'll probably want to let some good solvent/bore cleaner soak in there for at least several hours to act as a chemical cleaner prior to brushing.
In the meantime, I wouldn't worry too much about this, if I were you. Even guns with dark barrels can shoot OK. If yours does, you're basically done. If it doesn't its pretty improbable that just making the bore shine is going to fix the problem.
Incidentally, you didn't ask, but there are no cheap surplus having a Mosin rebarreled is effectively not cost-effective.0
