I have an AK in 5.45 and I see a bunch of the good deals on the ammo are on mil surplus cans of around 1080 rounds and they are as is much of the eastern bloc surplus ammo, corrosive. I can find some good shoot able quantities of 5.45 here in town but if I wanted to keep a can of surplus ammo around for that "rainy" day or if I just want to shoot off a bunch of rounds at the range or if for what ever reason ammo could no longer be imported would you guys see it as some thing that would be worth buying and shooting. I hear Windex will clean up corrosive ammo well because it has the ammonia in it so or soapy water will do the job to clean up the corrosive particles from the gun and the AK is a pretty simple system to keep clean. So corrosive ammo, shoot it or leave it alone. My main ammo will be for right now non corrosive Silver Bear and Wolf when I can get them.
