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

The grain weight system determines the mass of the projectile. More grains = much heavier projectile. This measurement applies to the complete weight of the projectile, including the coat, lead inside, and any penetrator or other filler product, such as the chemicals utilized in tracer rounds.
