'Grains' as an unit of action for weight goes all the way 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 = much heavier projectile. This dimension applies to the overall weight of the projectile, including the jacket, lead interior, and any type of penetrator or various other filler product, such as the chemicals made use of in tracer rounds.

(https://profiles.xero.com/people/ammunitiondde)For reference, the weight of a paper clip has to do with 16 gr.
