I have a cut bank on a curve that I will cut into and build up with my back hoe, but I want to have a set up where I can recover bullet to see how they open .I will use jugs of ballistic jell or wet saw dust but if it goes on through. Building your own range is more fun than I though it would be,I turned around yesterday and there was a wobble knee fawn standing on the edge of the woods watching me. Lee
