Will a .22LR destroy Mild Steel?

Today I demonstrate if a shooter can use mild steel to train on. Targets are 10mm British-made mild steel plates set up at 20m from the firing point. *PLEASE NOTE* This is ONLY for .22LR. The shooting occurred at KENTUCKY EAST Firearms & Archery Club's shooting range based on the Isle of Sheppey United Kingdom. All safety protocols were followed under UK law *For Information purposes only*
