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


The grain weight system measures the mass of the projectile. Much more grains = larger projectile. This dimension uses to the complete weight of the projectile, consisting of the jacket, lead interior, and any kind of penetrator or various other filler material, such as the chemicals used in tracer rounds.


(https://youbiz.com/profile/ammunitiondde/)For referral, the weight of a paper clip is about 16 gr.
