Goex Cannon Black Powder is a special granulation for optimum Cannon performance. While Goex has improved manufacturing processes and material quality, they have manufactured black powder using traditional materials to provide the same great ignition characteristics and uniform speed that master shooters and hunters have relied on for over 200 years.
Warnings from the Manufacturer:
- Do not exceed the loads displayed in the reloaders guide.
- Never mix any two powders regardless of type, brand, or source.
- Never substitute any smokeless powder for Black Powder or any Black Powder substitute.

Tested this head-to-head with ffg grade in my small yacht cannon. While ffg is louder up close, the Cannon grade throws a deeper, rolling boom that echoes off the mountains beautifully. It’s the ultimate sound for celebration fire.

Some people try to use mixed ffg or ffg grains in small cannons, which leaves a ton of unburnt powder and a sticky mess. Goex Cannon grade burns incredibly uniform for its size. It makes swabbing out the bore between shots much safer.

When calculating safe grain weights for custom-built signal mortars, predictability is life. Goex has been doing this since 1802, and their lot-to-lot consistency is unmatched. My pressure testing numbers track perfectly with every new batch.

There is nothing like the classic smell of real black powder at an outdoor range day. It brings out a ton of onlookers whenever we pack the miniature cannon. Cleans up easily with basic hot, soapy water when you’re done.

The large, gravel-like kernels flow easily through heavy volumetric powder measures without getting crushed or stuck. It makes filling heavy cardboard coin-roller tubes for cannon cartridges fast, uniform, and safe.

Our historical group bought a bulk shipment online for our summer events. The smoke generation from Goex Cannon is absolutely spectacular and stays authentic to the period. It functions flawlessly in both our mortar and signal cannons.

I keep my powder stash inside a certified wood-lined magazine box in my unheated garage locker. Even after sitting through a brutal Canadian winter and a hot summer, a batch from last year performed identically to a fresh bottle.

While it’s labeled for cannons, I actually use it for my oversized 4-gauge shotgun and heavy sub-bore rifles. The large grain size keeps peak chamber pressures low and manageable while safely pushing massive lead balls downrange.

Finding real black powder online can be a chore with modern restrictions, but I’m glad Canadian shops still support us. This Goex stuff is rugged, reliable, and exactly what is needed to safely feed vintage muzzleloaders.

I use this exclusively for a full-scale 12-pounder replica cannon. The massive, coarse granules provide the perfect slow pressure curve needed for large bores. It gives a beautifully deep thud rather than a sharp crack, which is exactly what you want.

You cannot use substitute powders like Pyrodex safely or effectively in full-sized cannons. This real American-made Goex Cannon grade ignites flawlessly every single time. It’s getting harder to find online in Canada, so when it pops up, I buy a case.

Took the signal cannon out to the lake on a miserable, humid morning. Traditional black powder can absorb moisture fast, but Goex’s grain glazing is top-tier. It caught the spark from our fuse instantly and went off with authority.
