If you hit it with a bit of old school windex and swab it the ammonia stops the reaction. It's not a replacement for a good cleaning but it'll keep it from corroding on the way home.

 

Most russian milsurp ammo is corrosive.

I had an old time match shooter tell me "just shoot a few non corrosive after, it'll flush out the corrosive stuff", don't know if that's true, but he claimed all the old timers did that.

Nope, just use the Windex method. It is easy and works.

True, they told them if they didn't have hot water handy to whiz down the barrel.

Just because the powder is non-corrosive doesn't mean the primer is.  Korean 30 Carbine rusted up the barrel of my commercial M-1 carbine.  Greek surplus 30-06 also caused some rust in my Garand.

 

My rule is to treat ALL foreign surplus ammo as corrosive regardless of what the box says.

I've heard people say that if you shoot a few rounds of jacketed after shooting lead bullets, it will clear all the leading out.

 

I don't believe that one either.

I remember some 20 years ago there was a lot of Egyptian 9mm Luger ammunition floating around.   Being an old black powder shooter and in an abundance of caution I'll only shoot it through my chromed Browning High Power because I figured that is the easiest gun to break down and really clean thoroughly.
