Gonna buy at least one soon. But none of the public ranges will let you shoot anythng but paper. Just gotta join a local club that allows steel. And BTW the most fun is that little bitty square target that you can flip over the 2x4 if you hit it just right! Can't wait to put a few 8mm Mausers down range at all of them!
I have seen people shooting their own steel at ECPR. Not sure what the rules are, but you might send them an email...
