With the high cost of lead going out of this world, I decided to design a bullet stop and try and recover some of that lead. I wanted it portable and not to heavy yet be able to stop up to a .44 Mag. handgun. Kind of hard to see but here it is.
I drew the side view of the bullet trap without the sides on it so you could see what happens to the bullet after it hits the back piece of steel. The bullet hits the steel and is directed down to the opening in the metal 6" pipe. It goes thru the opening and travels around the inside of the pipe and eventually hits the piece of steel that I have welded on the inside and hopefully stays in the pipe. The whole backstop sits on basically a sandbox so if some of the bullet fragments then it will get caught in the sand. At the end of the day, I remove the end cap from the pipe and dump out the bullets/fragments and reuse the lead again next time.
You could drill a hole on each side in the middle of the side frame and put a steel rod thru that I have welded metal targets (sheep/gophers/bird etc) so when the kids shoot it with there .22's etc the targets would spin. Remove the rod and you could now use normal paper targets. Do you think it will work?
