Muzzleloading Black Powder. We prefer using a synthetic black powder because it is less volatile and burns cleaner. Our most preferred is #1 Skirmish Powder found on the PowderInc.com link on our website. It can be ordered and shipped to your door in 5, 10 or 25 pound amounts. Call them, they are great people to work with. It is a course grind CANNON GRADE. Tell ‘em, we sent you & they will know just what you need.
Most Muzzleloading retailers offer finer grinds for the rifle shooters. However they work well in our Cannons. Always purchase grinds as course as possible & will be marked Fg or FFg. While in a pinch you can use FFFg, but they are even finer & you will have more residue and waste as they do not burn as efficiently. FFFg is more for the Pistol folks. NEVER use a FFFFg. They are for the Flint Lock folks.
HODGDON’s Triple 777 brand makes an excellent sulfur free powder in Fg & a FFg and the Pyrodex brand makes several good synthetics as well. A good dealer will know other brands to recommend as well. Always let them know you are shooting a cannon.
