My old movable backstop was made out of 9x11x1" hardwood. It took .177 and .22 all day with no issues but after a while .25's were punching though, so for safety I made a new one today. This is 9x11 made out of 4x4's with three 3x11x3/8 pieces of hardened steel on the back.
I welded a 1/2" steel rod to a 9x9 steel plate then put a handful of bricks on it for steadiness. Final touch was to paint it green to blend into the firing line in my woods.
Here is a leftover piece of the steel after it was hit at 20 yards with my Impact on Max with a 33 grain King Heavy. As you can see by how flat the metal is laying on the desk, there isn't any deformation to the steel at all. I can feel a minor change on the surface of the steel where the pellet hit, but the pellet really didn't do anything other than disintegrate when it hit. This is tough steel - it took 3 new metal cutting blades for my Sawzall to make the 3 3" cuts across the steel to get my 3 11" pieces. Back to no worry shooting....
You can get this steel from Lowes for about $18 for a 3x36" piece.
