I do some backyard shooting and my guns aren't too bad at all. Problem is I have 3 sheets of plywood and have adhesived about a 1/3 inch thick rubber mat to the wood but the pellets seem to easily make it through to the wood and have a wallup when they hit. I didn't really care much but I guess one of the neighbors was getting rather curious what thr sound was so I need to quiet the hits down some more.
