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


History is trendy. A typical myth is that 'grains' describes the variety of grains of gunpowder or propellant in a cartridge. That is completely inaccurate. The grain weight system determines the mass of the projectile. Much more grains = larger projectile. This measurement relates to the total weight of the projectile, including the coat, lead interior, and any type of penetrator or various other filler product, such as the chemicals utilized in tracer rounds.


(http://localpartnered.com/directory/listingdisplay.aspx?lid=27532)For recommendation, the weight of a paper clip has to do with 16 gr.

However there's another aspect that we have to take into consideration when choosing a grain weight for our ammo.

Both of these grain weight cartridges will execute well in manufacturing facility 9mm hand guns, to typical gun ranges (up to 50 yards). 115 grain rounds are one of the most typical (and as a result least expensive).
