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

History is trendy. An usual myth is that 'grains' describes the variety of grains of gunpowder or propellant in a cartridge. That is completely wrong. The grain weight system gauges the mass of the projectile. Much more grains = much heavier projectile. This dimension puts on the overall weight of the projectile, including the jacket, lead interior, and any kind of penetrator or various other filler product, such as the chemicals used in tracer rounds.

(http://localposted.com/directory/listingdisplay.aspx?lid=24785)For reference, the weight of a paper clip has to do with 16 gr.

Just how does this associate to grain weight? Imagine you get on one of those play ground carousels, the ones with bars you hold on to while it rotates. Or a circus ride where you're strapped to a board, encountering inwards, which rotates actually fast. When it's spinning gradually, you don't really feel a lot, and it's very easy to hang on.

However there's an additional aspect that we need to think about when selecting a grain weight for our ammunition.

Rate is affected by a few major factors, including the type and amount of propellant (gunpowder), barrel length, and bullet weight.

These aspects, integrated with twist rate, identify how steady (exact) a projectile will certainly be, how much it can go, and how fast it will certainly reach it's destination. If you're like most gun owners in the United States, you're probably shooting manufacturing facility ammo out of factory-spec guns. As factory ammo is really standardized, there are tried and tested grain weight cartridges for the most prominent calibers: Don't be perplexed by the cartridge classification (Luger, Parabellum, 9x19mm).


The most common grain weight rounds for 9x19mm cartridges are 115gr and 124gr. These are commonly lead core, fully jacketed (FMJ) rounds. Both of these grain weight cartridges will carry out well in manufacturing facility 9mm hand guns, to normal handgun distances (up to 50 backyards). 115 grain rounds are the most typical (and as a result least costly).
