I shoot my air rifles almost every day or night. I needed cheap light weight pellet traps for my shop and basement. My shop I shoot 14 yards indoors and up to 35 with the garage door open.
I take motor oil boxes from the dumpster and pack them with layer after layer of cardboard cut to fit tight.
All the cardboard comes from a paper only dumpster behind our local Target retail store. Most big retail stores have a dumpster just for clean cardboard boxes folded and stacked neatly. Also a great source for free boxes if you are moving. The only other thing I add is a 1/8" piece of roofing rubber that I grabbed out of a roofing companie's trash cut to fit and placed between the bottom of the box and the first layer of cardboard. You could use a piece of wood if needed. I shoot these alot and haven't had a problem with shoot though yet even shooting in the same spot over and over.
That's 50 shots in the same one inch area with a 14 ftlbs spring gun @ 14 yards.
Back side of box shows no shoot through. These probably won't last for 20+ ftlbs guns but even at 10 yards in my basement they have held up so far.
And they are free. Takes about 20 min. to make one once you gather up the supplies. They are almost silent also. Once they get too shot up ,just throw them away. I have made six so far and have only replaced one- and I reused the piece of roofing rubber. Also made one from a bigger box for anti freeze.
