Soon after I got my first Mosin Nagant, I picked up some cheap surplus at a gun show. I think it's 1952 Bulgarian light ball. It looks really dirty and when I shoot it, sometimes I get "blowback" in my face. It's not harmful, but anticipating it makes being accurate difficult. I stopped shooting it for a few years, but decided to give it another go this weekend. It happened on one out of five rounds. Here are the pictures. What exactly is happening? What term should I Google to get more information? Thanks for any help.
