I count 6 hits on the wood, zero on the paper . I had a duct seal trap many years ago worked great but it got so heavy I couldn't move it or get the pellets out. I just use a box stuffed with rags now, every so often I clean it out build another one and start over good for about 10 to 1500 shots.Nice job on the box now put a few rounds on the paper
... I just break it apart remove the lead ball it back up and keep on shootin...
