I don't know, maybe that the guy does have some sort of stop beyond those trees, and is just trying to show those, less experienced shooters the damage it can cause. Maybe there is a hill beyond those trees. I don't know. Just before people comes on here, acting like they are range officers, they should have asked him first. I don't know the guy, but from his post's subject of safety first, seems he has an idea. Probably better then alot of posters. Maybe not.
