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


The grain weight system measures the mass of the projectile. Much more grains = heavier projectile. This dimension applies to the total weight of the projectile, including the coat, lead inside, and any penetrator or various other filler product, such as the chemicals utilized in tracer rounds.


(https://justpaste.it/i7fjx)For recommendation, the weight of a paper clip is about 16 gr.
