'Grains' as a system of measure for weight goes all the method back to ancient times, and stands for the weight of a grain of wheat


The grain weight system measures the mass of the projectile. A lot more grains = larger projectile. This measurement applies to the overall weight of the projectile, including the coat, lead inside, and any type of penetrator or other filler material, such as the chemicals made use of in tracer rounds.


(http://localbrowsed.com/directory/listingdisplay.aspx?lid=83218)For recommendation, the weight of a paper clip is about 16 gr.
