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

 

 

 

Background is amazing. A common misconception is that 'grains' describes the number of grains of gunpowder or propellant in a cartridge. That is completely wrong. The grain weight system determines the mass of the projectile. A lot more grains = larger projectile. This measurement puts on the total weight of the projectile, including the jacket, lead interior, and any type of penetrator or various other filler material, such as the chemicals made use of in tracer rounds.

 

 

 

(https://www.slideshare.net/AmmunitionProLLC)For reference, the weight of a paper clip has to do with 16 gr.

Both of these grain weight cartridges will execute well in factory 9mm handguns, to normal handgun distances (up to 50 lawns). 115 grain rounds are the most common (and for that reason least costly).
