My bullet trap is made of 3/4 inch steel plate set at an angle. When the bullet passes through the target, it goes into the trap strikes the steel and is deflected downward into a sand trap where they come to rest. All you do in the spring is sift the sand trap and you can recover a great deal of the lead. Although every once in a while I will find a slug about three to six feet straight out in front of the trap. Why some of them will not deflect is beyond me.

Behind the trap is another 1/4 steel plate and behind that is a log wall. After that just acres and acres of my woods. The reason I built the thing is I was cutting an actual road into the woods with the muzzleloaders. It is of no surprise to some the size of tree that a few hits from one of these big bullets,and then a wind, can bring down. I would look into the woods prior to the trap and wonder what tornado when through that small area...
