'Grains' as an unit of action for weight copulates back to ancient times, and stands for the weight of a grain of wheat


Background is cool. A common misconception is that 'grains' refers to the variety of grains of gunpowder or propellant in a cartridge. That is completely inaccurate. The grain weight system gauges the mass of the projectile. More grains = heavier projectile. This dimension uses to the complete weight of the projectile, consisting of the coat, lead inside, and any type of penetrator or various other filler product, such as the chemicals made use of in tracer rounds.
