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

History is amazing. An usual misconception is that 'grains' describes the variety of grains of gunpowder or propellant in a cartridge. That is entirely inaccurate. The grain weight system determines the mass of the projectile. A lot more grains = much heavier projectile. This dimension relates to the complete weight of the projectile, including the jacket, lead inside, and any type of penetrator or other filler material, such as the chemicals used in tracer rounds.

(http://businessezz.com/directory/listingdisplay.aspx?lid=114654)For recommendation, the weight of a paper clip has to do with 16 gr.

However there's an additional aspect that we have to consider when picking a grain weight for our ammunition.

The most common grain weight rounds for 9x19mm cartridges are 115gr and 124gr. These are typically lead core, fully jacketed (FMJ) rounds. Both of these grain weight cartridges will perform well in factory 9mm handguns, to typical gun distances (as much as 50 backyards). 115 grain rounds are one of the most usual (and consequently least costly).
