conversion for .22 LR. Ammo was, RN lead military issue. I've seen some guns go through 5000 rounds in a couple of days, then, about 1 month later the same gun would be on the range firing standard 5.56 ball ammo without a hitch. Does that mean anything. Certainly the lube would be different but lube would be blown down the tube to the carrier key. I had this experience and I still don't know.
