Partially 2 of our information to blackpowder weapons, we lined one half of the accuracy equation: projectiles. The powder and primers you employ to ship your rounds downrange matter simply as a lot. The suitable mixture will make sure you get acceptable chamber pressures – not an excessive amount of, which will be catastrophic, and never too little, which leads to poor efficiency – to supply optimum velocities and accuracy downrange.

Selecting Blackpowder
Selecting the correct powder on your muzzleloader means contemplating three key selections:
- Selecting powder or a powder substitute
- Choosing a granulation measurement of every grain
- Choosing loose-pour or pelletized powder
Blackpowder vs. Powder Substitute
Conventional blackpowder is very reactive. It ignites simply, making it the popular selection for conventional muzzleloaders utilizing exterior percussion caps or flintlocks for ignition. However conventional powder can also be excessive corrosive. Intensive cleansing is required after every use, lest you undergo a severely pitted barrel and chamber. Blackpowder substitutes are most popular as a result of they’re much less corrosive.
In lots of circumstances, substitutes have grow to be extra widespread than conventional powder. If you happen to choose much less cleansing and upkeep, it’s value giving a substitute propellant a strive. However, in the event you discover you’re battling ignition when firing a flintlock or conventional percussion rifle, common ole’ blackpowder stands out as the answer.
Pyrodex
Pyrodex, the commonest and reasonably priced substitute, makes use of a decrease share of sulfur and saltpeter, whereas incorporating over compounds, like potassium perchlorate, sodium benzoate, and dicyandiamide. Though flamable, these compounds are much less delicate to ignition sources, making them safer to move and deal with. When ignited, Pyrodex is, in actual fact, extra energetic per unit of mass than blackpowder – however, as a result of this powder substitute is decrease in density per cubic inch, its web power launch means it may be simply substituted for blackpowder utilizing a 1:1 ratio. In different phrases, a rifle that requires 90 to 150 grains of black powder can be full of precisely 90 to 150 grains of substitute, and nonetheless obtain the identical stage of power. Pyrodex prices, on common, the identical per unit as blackpowder: About $19 to $23 per pound.
777 (“Triple 7,” or “T7”) Substitute
Triple 7 powder is taken into account a higher-quality propellant substitute to Pyrodex. Shooters declare Triple 7 leaves behind much less residue than Pyrodex and usually makes swabbing the bore and eradicating fouling a neater process. However T7 propellant is costlier, too. Triple 7 is, on common, roughly 50% costlier than black powder an Pyrodex, averaging $33 to $35 per pound.
Blackhorn 209 Substitute
Blackhorn 209 is taken into account the very best high quality, and most costly, propellant substitute. It’s considerably costlier than Triple 7, blackpowder, and Pyrodex. However these prepared to spend the cash – as much as $75 for half a pound – declare that it supplies noticeably higher accuracy and efficiency, with larger velocities pound-for-pound than some other propellant, together with blackpowder. Blackhorn 209 can also be practically smokeless, offering a clear burn and forsaking little to no residue nor fouling.
However, like most subjects in regards to the perform of firearms, propellant choice and the ensuing efficiency is commonly subjective, or at the least distinctive to the gun, the shooter, and the projectile. It’s greatest to check numerous propellants to substantiate which supplies one of the best stability of value, efficiency, and cleanliness.
Blackpowder Grain Measurement
Grain measurement performs an necessary position in any powder’s combustibility: the smaller the grain measurement, the extra floor space there may be, relative to the whole mass of the powder. Meaning the smaller the grain measurement, the quicker the powder turns. Grain measurement is only one issue of the equation. There are just too many different components – grain form, density, graphite content material and powder purity, inclusions of creosotes, burn temperature – to rely solely on powder granule measurement to find out efficiency. However comply with the final pointers beneath, and also you’ll have constant efficiency with out the danger of blowing up your barrel. For conventional black powder, grain measurement is measured by F’s: One “F” on the label denotes a rough grain. The extra F’s on the label, the finer the grain
- Fg: The coarsest grain. Utilized in hobbyist cannons, muskets, and rifles with a bore diameter of .75 or larger. It’s additionally used for shotguns which are 10-gauge or bigger.
- FFg: Medium grain. Used for rifles with bore diameters of .50 to .75. Additionally used for 20- to 12-gauge shotguns, and pistols with bores .50-cal or larger.
- FFFg: Fantastic grain. Utilized in all blackpowder weapons with calibers beneath .50.
- FFFFg: Additional-fine grain. Used as a primer powder for flintlock pans. Do not use FFFFg powder as a major cost — you’re more likely to expertise a catastrophic failure.
Powder substitutes are even less complicated, and are marked by the next:
- RS: Used for rifles and shotguns. Equal to FFg powder.
- P: Used for pistols. Equal to FFFg powder.
Unfastened vs. Pelletized Powder
Pelletized powder affords one benefit: comfort. Particular person pellets are fashioned to carry a selected variety of grains, which affords simpler measuring. They’re additionally faster to load and require no powder measure or flask. However pellets present no measurable profit over free powder relating to ignition, velocity, and accuracy. Pelletized powder can also be costlier than free powder.
Primers & Percussion Caps
The primer or cap used to ignite your powder cost is as necessary because the powder itself: a scorching, constant ignition temperature ensures a fast and constant cost burn, producing predictable velocities, which interprets into higher accuracy. Save for flintlocks, which depend on free pan powder, there are three varieties of igniters used for all muzzleloaders: The fashionable 209 primer, giant rifle primers, and conventional percussion caps.
209 Primers
The 209 primer was adopted by the muzzleloading world to offer hotter burns and extra dependable ignition than conventional caps. They’re utilized in all inline muzzleloaders, and a few conventional muzzleloaders that will in any other case use a cap are actually being made to simply accept 209 primers. The 209 is used because the primer for contemporary shotgun shells. This mass manufacturing makes it an affordable possibility for muzzleloader ignition. 209 primers are made as magnum primers and normal primers. The previous is appropriate for igniting much less reactive substitutes (like Blackhorn 209) and pelletized powder, which will be harder to ignite. Customary primers are appropriate for conventional blackpowder, Pyrodex, and Triple 7.
Massive Rifle Primers
The VariFlame conversion equipment is a comparatively new system that permits a muzzleloader to make use of a big centerfire rifle cartridge primer for ignition. These trendy primers burn hotter and quicker than 209 primers and caps. At the moment, this technique is designed for the Paramount Pro Series Rifles from CVA. These rifles are made to burn giant powder costs to acquire extremely excessive muzzle velocities (as much as 2,200 FPS), affording sub-MOA accuracy at 300 yards or extra.
Percussion Caps
Percussion caps have been the unique primers used on conventional muzzleloaders, changing the flintlock motion within the early 1820s. They’re nonetheless used right now for conventional percussion handguns and lengthy weapons, together with replica rifles and muskets. There are three frequent percussion cap sizes: #10 caps, that are used primarily for pistols; #11 caps, that are used for rifles; and musket caps, that are, because the identify implies, are used on smoothbore weapons.
