Yes, I've got several and I shoot them sparingly with standard off-the-shelf Rem or Win. or the various cowboy action loads. The caliber is .32 S&W (not .32 S&W Long or .32 Colt).
You can also reload for it, I bought a hundred brass and a few hundred bullets when I got mine a couple of years ago. It's a cool little gun to shoot, the trigger pull is quite heavy, but not all that bad. Just stick to buying the stuff for cowboy shooting. You can check here and see what's in stock at MidwayUSA.
32 S&W standard loads.32 colt is the S&W with a dif bullet.they were jealous of there names so smith would not put colts name on there guns and colt the same.Smith did not put colt on there guns till after WW2????
