Corrosive ammo

Last Sunday I fired some corrosive military 7.62x25 ammo in a Polish TT33 Tokarev then zipped the pistol in a plastic bag so as not to contaminate the shooting bag. On Monday afternoon I went to clean the barrel and found a thin film of brown rust in the bore.
After cleaning the original, unchromed barrel, it was set aside for a chromed Chinese barrel that will be used hereafter in that pistol.
I was reminded how destructive corrosive 30-06 and .45 ACP ammo was
in the Army. Army bore cleaner did NOT do a proper job.

    What part of corrosive ammo is corrosive? Is it the powder or what?

    It is the primer.
    It contains salt.
    If you use ammo with corrosive primers and wash the barrel with hot water it desolves all the salt. Or, mix one part Ballistol and 9 parts water in an old Pepsi/coke bottle and pour some down the bore.
    Now clean it normally and save tons of money while not harming your gun.
    I only use corrosive in bolt guns.
    I believe corrosive in gas guns requires way to much effort to justify it

    In general, is a primer made with Potassium Chlorate, instead of Lead Azide (really old ones were Mercury Fulminate) Potassium Chlorate burns to Potassium Chloride, a first cousin to table salt. It is not soluble in standard bore cleaners, but IS soluble in water- which is why you see folks scrubbing bores with Windex, soap, hot water, etc.

    A friend told me last week when he uses the corrosive ammo he wipes out the barrel with Windex, I've been around for a while and I had never heard of Windex on corrosive. He swears by it.???????????????[:D][8D][8]

    Windex? Yep. Ammonia and water. Put a shot down the bore at the range, brush, patch. When I get home, they get a quart of HOT water thru the bore, little dish detergent on the brush, another quart of HOT water, dry patch, wait 5 minues, lightly oiled patch. Seems to work- have been shooting Mausers, MNs, SMLEs and SKS's with a LOT of corrosive ammo- bores are still excellent.

    Sweets 7.62 solvent also dissolves the corrosive salts, along with the copper fouling. Might as well kill two birds with one stone.

    Way back in WW 2 most of the time in training we used G.I. soap and
    hot water for cleaning corrosive primed ammo. With the exception of the .30 M-1 Carbine all usual small arm ammo was corosive. Also there was
    the cans of G.I. bore cleaner (including the small can, about 3 ounces) which fit into a M-1 clip pocket in the cartridge belt. It was a kinda
    milky like liquid which was also great. It is no big deal cleaning up
    unless you are lazy. But we made sure it was cleaned within 24 hours
    or less if possible. Look at how many M-1 rifles are still around from
    WW 2. Granted, many were rebarreled but the majority of these were "battlefield pickups" and not cleaned in time. When ones life depends on a functioning weapon it get cleaned.
