Cheap option is a local metal scrap yard and get them to cut some 3/8 or better scrap to size and punch a couple holes for hangers. I think I paid like $10 each for a couple bigger plates. May not last forever but at longer range I would think it is going to last my lifetime. Copper bullets def put a bigger dent in them.I’ve never bought steel… what should I get for a 7mm?
AR 500 is the good stuff, but not a cheap date
