I never had any real nasty trouble with the Korean M2 ball that I had, it was on clips in cloth bandoliers. It wasn't corrosive. It wasn't consistant. It wasn't accurate, in a 1903A3, M1 garand or P17 (Remington). After shooting a couple of bandoliers between them, I sold the rest of it to a fellow that wasn't to concerned with it's accuracy and didn't want the clips or bandoliers, as he was pulling the bullets and changeing out the powder and putting in hunting bullets. I bought all of the bullets back from him and we threw away the powder, it had a vey acidic smell and was dusty as well as some of the powder had become bonded together in the case. I could see this stuff becomeing dangerous soon. That was about five years ago. Also had a case of Brazilian from International firearms do the same thing, after blowing up a fine rifle and contacting them, they graciously, without any fuss offered to pay for all medical expenses, lost time at work and replace the rifle and the ammuition. Luckily, the only injury was a tiny piece of brass that manged somehow to make it around my glasses and get stuck on the white part of the eyball. If I find anything at all odd with milsurp ammo, it either gets returned, if possible, or broken up for components. Usually it is the powder breaking down, but whatever the reason, the chances of personal injury and damageing a fine rifle are just not woth the cost saveings. I'm not saying that I don't buy and use milsurp ammo, but I do shoot it first in a rifle that I wouldn't miss and that has been tied to an old tire and rim. bearhunter
