If you’re into historical reenactments, black powder shooting, or even just fascinated by the raw power of traditional firearms and artillery, you’ve probably heard of Goex Cannon powder. This isn’t your average powder for muzzleloaders—Goex Cannon powder is specifically engineered for use in cannons and large-bore black powder weapons. And yes, it’s as bold and powerful as it sounds.
In this in-depth review, we’re going to break down everything you need to know about Goex Cannon powder. We’ll talk about what makes it unique, how it performs in different conditions, who it’s ideal for, and how it stacks up against other similar powders. Whether you’re a seasoned enthusiast or just starting your journey into the world of black powder artillery, this article aims to give you a clear, honest, and comprehensive look at Goex Cannon.
What Is Goex Cannon Powder?
Goex Cannon powder is a type of black powder (also known as gunpowder) that’s specifically formulated for use in large-caliber weapons like cannons, mortars, and signal guns. It’s made in the U.S. and has been a go-to choice for black powder enthusiasts, reenactors, and historical artillery users for years.
The grain size of Goex Cannon is coarser than most other types of black powder. It’s even larger than Fg, which is typically used in rifles and muskets. This coarser granulation reduces the surface area of the powder, leading to a slower, more controlled burn. That’s exactly what you want when you’re firing off a full-sized cannon.
The burn rate, pressure characteristics, and safety considerations are all tailored toward the kind of large-bore weapons that require stable and consistent ignition without excessive pressure spikes. This makes Goex Cannon not only a powerful option but a safer one for those handling antique or reproduction artillery.
Goex Cannon Powder vs. Other Granulations
It’s helpful to look at how Goex Cannon compares to other popular granulations of black powder. Here’s a table for quick reference:
| Powder Type | Granulation Size | Intended Use | Burn Rate | Pressure Output |
| FFFFG (4F) | Very fine | Priming flintlocks | Very fast | Very high |
| FFFG (3F) | Fine | Pistols and small-caliber rifles | Fast | High |
| FFG (2F) | Medium | Rifles and shotguns | Moderate | Medium-High |
| FG (1F) | Coarse | Muskets and large rifles | Slower | Medium |
| Cannon | Very coarse | Cannons, mortars, large bore artillery | Slow and steady | Lower but sustained |
As you can see, the difference in granulation plays a huge role in how the powder performs. Goex Cannon stands out because of its very coarse granules. This means it ignites slower, creating a longer push behind the projectile, which is ideal for heavy artillery where you don’t want too much sudden pressure.
Key Features of Goex Cannon Powder
Let’s go over the standout features of Goex Cannon powder in a more detailed list:
Specifically Engineered for Artillery Use
Goex Cannon isn’t a general-purpose black powder. It’s been created with one thing in mind: large-bore firearms. Whether you’re using a full-sized Civil War-era cannon or a replica mortar, this powder is designed to give you reliable, consistent results.
Extremely Coarse Granulation
With its large grain size, Goex Cannon powder ensures a slower and safer burn. This is crucial for large barrels where too much pressure too quickly could spell disaster—especially with antique or reproduction cannons.
Stable Burn Characteristics
The powder burns evenly and predictably, offering great performance in a wide range of conditions. Whether you’re firing in humid weather or dry heat, you can count on Goex Cannon to do its job.
Clean Burn (Relatively Speaking)
Now, black powder is never going to be “clean” by modern smokeless standards. But Goex Cannon produces less fouling compared to some other coarser powders. That means less buildup, easier cleaning, and better long-term maintenance of your cannon.
Made in the USA
Goex has been a reliable name in black powder manufacturing for decades. Based in the U.S., their production standards and quality control are among the best in the black powder world. For many enthusiasts, buying American-made powder is a point of pride.
Widely Available at Specialty Retailers
Though it’s not something you’ll find at every sporting goods store, Goex Cannon is relatively easy to find through online black powder retailers or shops that specialize in historical shooting supplies.
FAQs
What is the grain size of Goex Cannon powder?
Goex Cannon powder is extremely coarse, significantly more so than even 1F (Fg) powder. It typically has a grain size of 4mm or larger. This makes it ideal for use in cannons and similar large-caliber firearms.
Can I use Goex Cannon powder in a rifle or pistol?
It’s not recommended. The granulation is too large and will not ignite reliably in smaller chambers. You’ll get inconsistent burn rates, poor accuracy, and possible misfires. Stick to 2F or 3F for rifles and pistols.
How should I store Goex Cannon powder?
Like all black powders, Goex Cannon should be stored in a cool, dry, and well-ventilated place. Keep it in its original container, away from heat sources, open flames, and moisture. Always follow local regulations for black powder storage.
Is Goex Cannon safe to use in antique cannons?
Generally, yes—as long as the cannon is structurally sound. The slower burn rate of Goex Cannon makes it a safer choice for old barrels, but you should always have an antique weapon inspected by a qualified gunsmith or artillery expert before firing it.
How does it compare to Pyrodex or other black powder substitutes?
Pyrodex and similar substitutes are often tailored for modern muzzleloaders and perform differently under pressure. Goex Cannon offers more traditional performance and is usually the preferred choice for those aiming for historical accuracy. However, it’s more corrosive and requires thorough cleaning after use.
Is it affected by humidity?
Yes, like all black powders, Goex Cannon can be sensitive to moisture. It’s less of a problem than with finer powders because the coarse grains don’t absorb moisture quite as quickly, but it’s still wise to store it properly and keep your powder dry on firing days.
Conclusion
If you’re serious about black powder artillery, Goex Cannon powder is one of the most trusted options out there. Its coarse granulation, reliable burn, and tailored design for cannons make it a standout product in a very specific niche. This isn’t a one-size-fits-all solution—it’s a specialized tool for a specialized purpose, and it does that job exceptionally well.
From historical reenactors to cannon enthusiasts and collectors of working artillery, Goex Cannon delivers the kind of power and performance you need to get the most out of your equipment. It’s not just about firing off a shot—it’s about doing it safely, accurately, and with as much historical authenticity as possible.
