Mosin Nagant Cleaning Question

    Took my hex receiver 91/30 out to the range today and absolutely loved shooting it. Even with surplus ammo I was really impressed with its accuracy (only got out to 100yrds this time.

    Anywho...got home and started cleaning it the same way I do all my guns. Hoppes #9 through the barrel a bunch of times on a swatch. Then at the end a swatch with Rem Oil. The cloth turned green after it went through the barrel....I'll be honest I am new to corrosive ammo, but was this some sort of reaction?

    google "corrosive ammo cleaning"

    it's not hard, but it is necessary

    Right, I guess my question is, does that mean the Hoppes #9 didn't clean the barrel properly if the final oil swatch turned green? Should I just put warm water down the barrel instead?

    Green is jacket fouling (copper) the Hoppe's was in the process of removing.

    It's not "instead", it's "along-with". Use the hot water to get rid of the corrosive salts, then clean as normal.

    Ok, I think I got it now. So the Hoppes won't get rid of the corrosive salts, use water for that then clean as normal. I just figured the Hoppes would have taken care of it.

    The use of corrosive surplus ammunition requires a different cleaning process.
    You have to neutralize the salts left in the bore & Hoppe's 9 won't do that.
    Rem Oil isn't the best way to go for a preservative afterward, either.

    There are several methods people use, running from hot water down the bore to Windex.

    I use Windex with vinegar on mine, works great.

    After that, I occasionally use a copper solvent followed by Break Free.

    Minimum I do is Windex followed by Break Free.

    Green on patches means there's still copper fouling in the bore.

    Don't forget to "wash down" the bolt assembly or you will be seeing rust very soon.

    I have CLP also, so that would be better than Rem Oil as the final rust barrier?

    Rem Oil has turned out to not be a particularly good rust preventer.

    Ok, thanks for the help all, I've never had any issues with cleaning, rust or anything in the past and this is my first experience with surplus weapons and ammo, pardon my ignorance.

    No need for any pardons, if you're new to corrosive ammunition you have to learn somewhere. :)

    Rather than warm water, used near boiling water to dissolve and flush the salts that cause corrosion out, then the hoppes , ect and get the copper/lead out.

    The hot water will heat the metal and dry itself, very quickly, so you don't have rusting issues with residual water.

    Very good, Carry on!

    If you use the boiling or very hot water with enough to warm the barrel to where you can barely hold it then stand it muzzle down with an air gap. The heat of the barrel will produce a chimney effect to aid in drying the bore moisture. Otherwise it could easily cool down with the last of the water still in the bore.

    I don't bother with the boiling water. Instead I use a bore mop soaked in water then a couple of drying patches then go straight to the CLP or copper solvents depending on how nutzy I want to get.

    I like the idea of the hot water thing though. One day I'll make up a cartridge casing that has a plastic hose line attachment soldered into the head so I can just insert in the chamber and have it hooked up to my hot water tap.

    I just pour water down the barrel, then wipe a patch wetted with hoppes, then a few dry patches till it comes out mostly clean. Good enough for me. Haven't had any rust issues on my Mosins yet.

    Hoppes No 9 will dissolve corrosive salts. Water is the best though.

    There is no magic in using Windex other than its mostly water.

    I use caribou's cleaning regimen.

    There are many different versions of fluids & methods that people use.
    I make no claims that mine is the only one, or the best one, to use.
    I just mention it as one that works.

    I use Windex with vinegar because it was recommended to me many years ago, it's more convenient than messing with hot water, and it works.
    I spray a small amount on a patch & run several through till the black lessens, then use a couple dry patches to get the liquid out, then either use a copper solvent followed by Break Free or just the Break Free, depending on how much I've shot.

    Spray the Windex on a bigger patch & clean other parts like the bolt & so on, followed by dry patch, followed by Break Free patch.

    No signs of rust on the four I've done it to.
    No magic.
    Just easy & my preferred method. :)

    If it's been a high round count, I may use a brush, too.

    My Mosin cleaning method is windex patches, dry patch, hoppes no 9, brush, dry patches (repeat if needed), hoppes oil. Also as said be sure to do a good cleaning of the bolt, especially the bolt face. I forgot that once and it wasn't pretty.

    I've used Hoppes to clean my Norinco SKS for years, including the period of time all I shot was corrosive Chi-com ammo. Also, note, I live in South Dakota, not exactly known for its low humidity. I've never had rust issues of any kind, and the bore is still pristine. Maybe other people have had different experiences, but Hoppes #9 has never failed me when shooting corrosive ammo thus far (roughly 20 years of shooting my SKS)
