huh ! you have solution for that.
Grab a box whatever size you want, put two or three layer of the thick clothes on the bottom of the box and test a few shot to make sure that the pellet doesn't go through then you are set to go. Especially, this Christmas there will be a lots of box from the gift so grab a few and make a pellet gun stoper. That would help you not to damage your wall.

Less penetration = less holes in the walls!!
