Bought a FN-49 many years ago. Had fired two rounds through rifle, sitting at bench, with my two buddies observing beside me. They had just walked away when the rifle fired out of battery and splattered brass fragments up and back, taking off my cap and embedding a small piece in my scalp. I was dazed for second and then came around and searched for the problem. The bullet was gone down the barrel, but just about half of the brass was left. The bottom part, rim, and about 1" was vaporized. With me sitting behind the rifle I was somewhat shielded but if my buddies had stayed where they had been, the blow back would have been in their faces. The fact they'd walked away made that the best day at the range for me. I have been leery of surplus rifle ever since.
