Ammo Manufacturing and Powder Measurement

Ammo manufacturers usually use grain as the unit of measurement. When you see the wood grain in ammo packagings, it usually refers to the weight of the projectile used. The reason why manufacturers show grain is because calibers also vary in weight.

The ability to measure the amount of gunpowder is helpful for forensics and reloading. Hence, manufacturers often add instructions on how much powder should be added to their ammunition if people want to reload it.

While some calibers have only one designated grain measurement, some calibers can have various grains depending on preference. For example, a 9mm ammunition can have a grain weight of 115, 124, and 147. The added weight does have an effect on the caliber.

Heavier bullets won’t be affected by wind as much as lighter ones. They also pack more power. However, they will travel slower and won’t be good for long-range shooting.

Therefore, the grain variation helps you choose ammo to fit your shooting condition.

More or Less Grain?

New reloaders oftentimes wonder about how much powder should they add. Some experienced reloaders often add a bit more powder to their ammunition. The reason for this is for higher accuracy since most shooters fire at close to medium range.
