corrosive ammo

shootlow
Maybe a stupid question but if you fire corrosive ammo and then soon after clean the bore properly will there still be corrosion?

Thanks

    I live in Florida. I just bought a in the waistband holster for my Ruger P-85. I wore it once last week because I usally carry my Ruger SP101. When I got home after being out all day, I pulled it out of the holster, because I never leave my guns in holsters. The gun had sweat on it so I sprayed it with Breakfree and wiped it down.

    I took The rounds out of the magazine today only to find out the primers were corroded mostly from the top of the magazine. What do you do to correct this? Wipe down the ammo every time I carry with this holster and how do I clean up the corroded ammo? The ammo is new Winchester 115gr. 9mm SilverTips with brass casing.

    Hello to the best of my knowledge there is no known way to look at ammo and tell. You could remove primer and send to a lab dangerous to both you and the lab. Best to not take a chance and if you want the ammo use it and clean gun every time like WE did when corrosive primers were all we had. There are plenty of older guns that had many rounds of corrosive shot in them with mint bores.Of course you can shoot a bunch of it in your gun not clean for 2 weeks then try to clean, if it aint pitted it wasn't corrosive. THIS is not my first choice. quote:"PRAISE THE HARDBALL GUN"

    I agree with Perry, no way to tell by looking.
    Good rule of thumb, if it is military surplus, it is corrosive. That goes double for commie milsurp, not to say that commie milsurp is bad ammo, lots of it is very good.
    You can pull the bullet and ammo and test the primer, as it is the primers that cause the corrosion.
    Take a four inch by four inch sheet of steel and clean it real good with a wire brush.
    "Shoot" it with your gun, using the primer only cartridge. Let it set out in a warm humid environment. My living room in these rainy NC mountains would be a perfect environment. For a comparison, "shoot" another piece of steel with a primer that you know to be non corrosive.
    The corrosive primer will rust up that steel in a few days.
    If it passes that test, shoot a few live rounds. Let the rifle set, in two days run a clean patch down the bore. Inspect for rust.
    Inspect again in 2 more days, inspect again in a week.
    If it is corrosive, one of your inspections will reveal red rust all over that patch.
    Swedish Mauser milsurp is non corrosive. Your Russian/Yugo I bet a dollar is corrosive.

    We use to use hot soapy water to clean the barrel of a rifle to get rid of the corrosive salt that corrosive primers generated. I would get a pan of hot water, some dish washing liquid. Then I would put the muzzle of the rifle about an inch or two into the soapy water, run a cotton patched jag down the bore until it just barely run out the muzzle of the rifle, then slowly pull the jag back up the bore until it gets to the chamber and then slowly pump it back and forth for about 10 to 15 times and you have eleminated the corrossion problem. Just be sure to remove the copper and then dry and oil the barrel good before setting her back up. Course, if you don't mind the smell, you probable can find the old military bore cleaner that was designed to clean the effects of the corrosive primer out and use that.

    All good answers. Short one is that I wouldn't advise you to take the bet offered unless you like to lose.
