That kinda seems to depend on the club. One I frequent allows pretty much anything as long as there is an effort being made to come in compliance, one of the ladies was shootin' a henry and a pair of single sixes, and borrowing a shotgun, nother guy showed up with a big ole' ruger double action just to see what it was all about, they let him use it as long as he shot it single action, but they did make him take the scope off! Another club will allow ya to use the range after the match with 22's. The situation hasn't risen at the others when I was there.
I have a suggestion, find someone with a rossi '92 in 357 and ask to borrow it long enough for him to try it out. I'd almost bet you'll start looking for one.
