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


The grain weight system measures the mass of the projectile. Much more grains = much heavier projectile. This dimension uses to the overall weight of the projectile, consisting of the jacket, lead interior, and any type of penetrator or various other filler product, such as the chemicals used in tracer rounds.

There's one more aspect that we have to take into consideration when picking a grain weight for our ammo. As hinted at above, bullet velocity, or the speed of the projectile, is a major variable when determining the very best grain weight projectile to make use of.
