Just a plain old TC Renegade or hawken is great and should be all legal. A peep sight makes it better yet for shooting but some say it is harder to hunt with. A 54 cal. roundball is 225GR. of lead @ 1,400 fps. You can make your own round balls with lead and a mould and your own patches . Black powder lasts forever too. Just find some #11 primers and go... Swab each shot with a damp patch and reload. I have not shot my inlines since I got my TC Hawken and Renegade.
