Corrosive isn't the issue with milsurp ammo, accuracy is. If you want stuff that goes bang, it usually works. I've used Turk 8x57 from the 40s with no problem. Accuracy was horrible to non-existent.
To test the accuracy of the mauser I was using, I loaded up some 185gr Corelokt bullets over 45 gr of IMR 4064 in Rem cases with a CCI 200 primer. A very mild load, and easily groups under 2 inches at 100 with that old rifle.
Machine guns are awesome until you have to carry one.
