Pyrodex is measured just like blackpowder is measured. A volumetric measure is adjusted to the required load and the powder is poured in. Ex. A load for a 50 caliber rifle calls for 90 grains of FFG blackpowder or 90 grains of Pyrodex RS. The measure is set to 90 grains, the powder is poured into the measure and then poured down the bore of the rifle.

There is no advantage to weighing charges of Pyrodex or blackpowder. Because these powders are very inefficient by today’s standards, volumetric measurement is the quickest, easiest and most accurate way to measure powder.

Pyrodex is lighter in weight than blackpowder and weighs only about 70% as much as blackpowder. However, because Pyrodex yields more energy per pound than does blackpowder, the same volume of Pyrodex gives similar performance to blackpowder. Pyrodex loads given in this manual for muzzleloading guns are measured by volume, not weight.
