'Grains' as an unit of action for weight copulates back to old times, and stands for the weight of a grain of wheat


Background is trendy. A common myth is that 'grains' refers to the number of grains of gunpowder or propellant in a cartridge. That is completely incorrect. The grain weight system measures the mass of the projectile. Extra grains = heavier projectile. This dimension relates to the overall weight of the projectile, including the jacket, lead interior, and any kind of penetrator or various other filler material, such as the chemicals utilized in tracer rounds.


(http://www.northlandhq.com/directory/listingdisplay.aspx?lid=70205)For reference, the weight of a paper clip has to do with 16 gr.
