'Grains' as a device of action for weight copulates back to old times, and represents the weight of a grain of wheat


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