Yep you shure can, just used the reamer not to long ago, easey to do, your going to like the max. Like canon6 said not a problem shooting 38 or 357 out of it just clean it after shooting, if I'm going to shoot both at the same time I'll shoot the max first then 357 and 38's last, enjoy it and let us know how it does, there are no dumb questions, ask away.
