Mt. Man,
I've carried an Interarms Virginia Dragoon in .44 Mag many times. I've yet to get the opportunity to Harvest a deer with it, but maybe this year I'll have the chance. I'm comfortable shooting to 45-50 yards with it on a deer, if the deer is holding still. This revolver is pretty heavy, but I don't mind carrying it.
I don't remember what I'm shooting out of it, and I'm at school and can't go look right now. All I know is that it's a 240 grain HP. I shoot the same thing out of a lever action. I have taken deer with that and It was a double lung hit, the deer went about 25 yards after being hit.
Good luck this year, I enjoy carrying mine and can't wait to get one with it
