Built these for our farm range, two layers of 3/8 mild steel welded together to get 3/4". Used mild steel because it was free and what was laying around, but hardened would have been better. These swingers are at 50-100-200 yards, so heavy not much swing with .22's...but center fires will move them. Deep craters are from .223 and .308....others are .44 mag and blackpowder rifle. Another thing that will help cut down plate deformation is stiffening up the back side as shown.
