Hi guys,
Has anyone heard about the dangers of using 7.62 x 39 corrosive surplus for Ruger mini 30?
I heard it destroys the barrel and mechanics of the gun.
Any feedback?

Boiling water is cheaper and works better ;)

Remember - the ammo is corrosive because it's a salt. Oil will only cover the salt and when it runs away, the gun will rust. I've never used ammonia, but pouring boiling water all over, then scrubbing not only cleans the gun, dissolves and removes the salt, but also heats the gun up so it self dries.

Soldiers were using hot water during the hay days of corrosive ammo. Ammonia works great but there is no scientific evidence that it works better than hot water.

I'm assuming you are using Czech surplus ammo??

Ruger does not warrant it's mini-30 with Russian (.310) ammo only Amercian made 7.62x39mm i.e Dirty Bird (.308) diameter...just a thought.
 
Would the corrosive military ammo all have bullets .311" diameter, and is the Ruger Mini 30 barrel only .308" diameter? Anybody know anything about this supposed .003" difference and it's effect on the rifle?
 
Most guns do not have a .308 barrel (though I read credible rumors that some of the earlier models did). Regardless, the .003 difference will cause no problems at all. On mine, if I stick the inside-measuring part of my calipers in the end of the barrel and wiggle them around till they seem drop off in some grooves, they read .309, and it certainly doesn't have any problem digesting mil-surp ammo, nor any problems digesting 150 grain .312 bullets in my handloads.

As for cleaning - for mine (and yes, I shoot lots of corrosive Chezch mil-surp in it) -- AS SOON AS I GET HOME FROM THE RANGE, I strip it down and do a hot water bath (pay special attention to make sure you get it through the gas port) using a toothbrush to clear out any grime from the nooks and crannies I can reach, then I patch the bore dry, followed by a couple of windex patches for good measure. Then, I dry it all out and once dry, I give all the parts a quick hose down with BreakFree CLP, and then reassemble. Haven't see a speck of rust on it yet, and I've been doing this for a while now.

Best of luck,

corrosive ammo

I;ve heard boiling water works great. and I;ve also heard but don;t hold me to it when some guys boil their water they put a little dish washing liquid in because it nutrilizes the salts so they say . please excuse the spelling . I myself picked up a few cans of GI bore cleaner . I;m sure it;s from the 1960ties but it works great . and I oil after . ps I try to have 2 cleaning rods one for stuff I shoot corrosive out of and the other one for non corrosive ammo . :D
