'Grains' as a device of measure for weight goes all the method back to old times, and stands for the weight of a grain of wheat


History is amazing. A typical myth is that 'grains' refers to the number of grains of gunpowder or propellant in a cartridge. That is completely inaccurate. The grain weight system determines the mass of the projectile. Extra grains = heavier projectile. This dimension puts on the total weight of the projectile, including the coat, lead inside, and any kind of penetrator or various other filler product, such as the chemicals made use of in tracer rounds.
