As ChamberdRound said they are mounds of dirt about 30-40 feet high as a backstop. I honestly can't see how my Brother-in-law, even being inexperienced, could have had his rifle at a steep enough angle to clear the backstop. He had his target setup about 30-40 yards down range, and even if he was legally blind there was no chance of him being that far off target. I was watching him through the first 20 rounds and he was shooting high but I helped correct his aim. As far as a staged incident, it's possible but it just too much of a coincidence that the round looked to be a 7.62x54R the same as my Mosin. The thing that kind of bugs me is that the round was fully intact and perfectly straight, I thought after traveling about 3/4 of a mile and going through a roof there would be some sort of mark besides rifling marks.
