I just completed re-building my .22 backstop. Originally, it was several bales of hay(also use it for my bow), backed up with 2 x 8's and 1/2" OSB board, then against a16" poured concrete wall. It is now backed with 6 layers of 2 x 8's or 6" of solid lumber and then a double layer of 3/4" plywood, again against a concrete wall.
I'm curious if anyone knows of the actual penetration of a .22 LR round.
