100-500 or so
Depends on the caliber. A .45 caliber pistol uses about 40 grains of black powder. Contact the maker's website and download the owner's manual for YOUR gun.
Black Powder.
Knight rifles website has the manual for this gun available to download, contains complete instructions and capacities for powder etc. www.knightrifles.com
To the best of my knowledge unless you are a convicted felon you can own a black powder gun.
Whatever the reloading manual has in it.

I imagine state laws vary on this but in Texas you do not have to call anybody to transfer a black powder gun.
Follow the instruction in the owner's manual. If you don't have one, contact Knight. Good advice, If you don't know how to do it get instruction from a local club member or black powder shooter. Your local gun shop may be able to put you in touch with someone. The loading is just like loading a shotgun shell. I use 60 grains of 2F powder, then an over powder wad or a shot cup depending on what I am hunting, then 1oz of ___ (fill in the blank depending on what you are hunting) shot, followed by an over shot card. Same as a shot shell but the barrel is the hull.
no rockets run on black powder (gun powder)
