Usually the best thing to use on those is lead bullets, second choice is the plated bullets like Berrys or Rainier, the lead core on those is soft and the plating pretty thin, so they react like a lead bullet when hitting a steel target. I would stay way back when using jacketed bullets, those things can bounce back at you, I recommend following their advice.
