I have a Rossi 357, eats everything i feed it including the aluminum cased Blazer .38s without issue. Not the same gun, but I'd say get a grab bag, order a few boxes of cheap 38s and see what runs.
Grab a scope mount and throw a red dot on there. Yeah yeah it's heresy but hitting a spinner or gong with it is too much fun not to. .38s are solid on smaller game as well.
