'Grains' as a device of action for weight goes all the method back to ancient times, and represents the weight of a grain of wheat


The grain weight system gauges the mass of the projectile. More grains = much heavier projectile. This measurement uses to the total weight of the projectile, including the jacket, lead inside, and any kind of penetrator or various other filler material, such as the chemicals used in tracer rounds.


(https://freeimage.host/ammunitiondde)For referral, the weight of a paper clip is around 16 gr. We know that grains are a measure of mass, and a lot more = much heavier, and heavy is excellent?
