'Grains' as an unit of measure for weight goes all the way back to old times, and stands for the weight of a grain of wheat


The grain weight system measures the mass of the projectile. Much more grains = heavier projectile. This dimension applies to the total weight of the projectile, including the coat, lead inside, and any penetrator or various other filler material, such as the chemicals made use of in tracer rounds.

Or in the instance of the circus trip, you begin to really feel much heavier. The more mass you have (weight), the much more you will feel this effect. The same impact occurs with bullets. The much heavier the projectile, the more effect a much faster spin will carry it. This is why you have a tendency to see slower spin prices for larger, slower projectiles, and much faster spin prices for lighter, higher velocity projectiles.

There's another factor that we have to take into consideration when choosing a grain weight for our ammo. As meant above, bullet speed, or the speed of the projectile, is a significant aspect when establishing the finest grain weight projectile to use. Speed is affected by a few major elements, including the type and quantity of propellant (gunpowder), barrel size, and bullet weight.


These elements, combined with twist price, establish how steady (precise) a projectile will certainly be, how much it can go, and how fast it will certainly reach it's destination. If you resemble many gun owners in the USA, you're most likely shooting factory ammo out of factory-spec guns. As factory ammunition is very standard, there are tested grain weight cartridges for the most popular qualities: Do not be confused by the cartridge designation (Luger, Parabellum, 9x19mm).


The most typical grain weight rounds for 9x19mm cartridges are 115gr and 124gr. These are normally lead core, totally jacketed (FMJ) rounds. Both of these grain weight cartridges will perform well in factory 9mm handguns, to normal pistol ranges (as much as 50 backyards). 115 grain rounds are one of the most typical (and for that reason least expensive).
