I reload the Wolf .45ACP steel cases, once. I then shoot them in situations where I'd be losing most of my brass anyway. No problems so far and I've shot three or four cases of these reloads. What's curious, is I've many Para Ordnance mags that really don't like to feed Wolf FMJ, what mystifies me is when I reload 230gr hard cast lead RN into these steel cases they feed as perfectly as any ammo does in the Para mags.
I met a guy at our club who was about the only other person I've ever seen picking up the Wolf empties. He said he reloads them same as brass -- until the case mouths split.
I discard any with any signs of rust and try hard to only pick up my own freshly fired ones. Note the Wolf .45ACP steel cases are Boxer primed. Winchester or Magtech or Federal are a great fit. PMC is too tight.
