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


The grain weight system gauges the mass of the projectile. Much more grains = much heavier projectile. This measurement applies to the overall weight of the projectile, consisting of the jacket, lead interior, and any kind of penetrator or other filler material, such as the chemicals utilized in tracer rounds.

These aspects, integrated with twist price, establish just how secure (accurate) a projectile will certainly be, just how much it can go, and how fast it will get to it's destination.

The most usual 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 hand guns, to normal handgun distances (as much as 50 yards). 115 grain rounds are the most typical (and consequently least costly).
