New target backstop can easily take punishment from all of air rifles: building and testing it

While running my newly modified Crosman 363 through the chronograph it became obvious that my previous ballistics trap setup was too small. I had a boxed bbq grill, never used, as the main ballistics trap, but it was too small. To compensate, I had been using hung pieces of plywood, and thick cardboard. Those no longer work, as the .22 cal pellets from the Crosman 362 with a metal breach pierced right through, and were lodging in my double-thick plywood sliding shed door. At the same time, I needed to build a target backstop, for my new 24 yard range, which had also been using thick cardboard and thin plywood as a backstop. So, even, though it was a very hot and humid day, it was time to get this out of the way. In this video, you'll see how I made this backstop, and some of the shots it easily withstood.
