Ivory powder measure used to provide a uniform amount of gunpowder for a muzzle-loading firearm before cartridges were available. A powder measure is a device for dispensing consistent amounts of smokeless powder or black powder as charges for handloading cartridges used as small arms ammunition. a typical volumetric powder measure
A grain is a unit of measurement of mass, and in the troy weight, avoirdupois, and apothecaries' systems, equal to exactly 64.798 91 milligrams. It is nominally based upon the mass of a single ideal seed of a cereal .
Black powder substitutes are measured by volumetric measurement techniques, not in grains on a scale, due to the difference in density compared to black powder. For example, to measure a "60 grain equivalent" of black powder substitute suitable for use in a muzzleloader rifle, one uses a volumetric measure that produces a volume of black powder ...
A cartridge, [1] [2] also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (smokeless powder, black powder substitute, or black powder) and an ignition device within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of ...
Grains are used worldwide for measuring gunpowder and smokeless powder charges. Historically, the dram (27 + 11 ⁄ 32 grains; not to be mixed up with the apothecaries' dram of 60 grains) has also been used worldwide for measuring gunpowder charges, particularly for shotguns and large black-powder rifles.
C-6–C-7 The dram apothecaries is equal to 3 scruples (s ap or ℈) or 60 grains (gr), [5]: C-7 or exactly 3.887 9346 grams. [5]: C-14 "Dram" is also used as a measure of the powder charge in a shotgun shell, representing the equivalent of black powder in drams avoirdupois. [16]

The term black powder was coined in the late 19th century, primarily in the United States, to distinguish prior gunpowder formulations from the new smokeless powders and semi-smokeless powders. Semi-smokeless powders featured bulk volume properties that approximated black powder, but had significantly reduced amounts of smoke and combustion ...
