Need a little more info. Is this gun a percussion or flintlock? If percussion then you have options as to different powders, such as Pyrodex or black. If a flintlock then you should only use real black powder. Of course with the latter you'll need flints. A Renegade has a 1/48 twist barrel so you have options as to ammunition there as well. It will shoot round balls as well as conicals with pretty good accuracy. Of course for either you will need a cleaning jag, ball puller, patch worm (for removing stuck patches), cleaning solution (easily made yourself), patches for cleaning/lubricating, etc. If shooting round balls you will need lubed patch material for the loading process.
