'Grains' as a system of measure for weight copulates back to ancient times, and stands for the weight of a grain of wheat


The grain weight system gauges the mass of the projectile. More grains = heavier projectile. This dimension applies to the total weight of the projectile, consisting of the coat, lead inside, and any type of penetrator or various other filler product, such as the chemicals used in tracer rounds.
