Had something weird happen on Saturday. I picked up a new to me 1944 Mosin 91/30 to keep my M44 company. Since we were heading directly to the range after the gunshow, I stopped by some random booth and picked up two packs of 20 round light ball in little wrapped paper packages. I later found out that it was of Chinese manufacture. Well out for the first five rounds, three rounds fired perfectly, two didnt. I thought it was the rifle and I reinserted the rounds. Still no fire. Popped them out, could see the primer was dempled but the rounds did not go off. Tossed them onto the field and loaded 5 more rounds. Same thing happened, this time only 2 good rounds out of 5. Same issue. I looked up Chinese x54r reliability and people had generally good things to say about it. Was there something wrong with the ammo, or should I look at the rifle? Anyone have any experience with this?
