I took a M1941 rifle to the range that I had for the typical three day pre-purchase inspection. I noticed that it functioned with a great deal of violence, damaging the cases as your photos show and flinging them many feet to the right. After just a few rounds, the same rifle began to literally fall apart in my hands. It would not hit a standard pistol bull's eye at 25 yards. This was one sad rifle, and I sent it back to the seller. The next one was in virtually new original condition, and I have it to this day. There is all of the difference in the world between the two guns. The "new" '41 is very accurate and completely reliable. The action seems to function almost as an afterthought. The rifle fires, and then the action gently cycles, leaving a neat pile of undamaged brass just a few feet away. I bought a considerable amount of surplus Danish M2 ball when it was avialable and have used this exclusively.
