What is grain in ammo?

Grain is a unit of measurement used to describe the weight of bullets and gunpowder in ammunition. One grain is equal to 1/7000th of a pound. The weight of a bullet is typically measured in grains, with common bullet weights ranging from 50 to 250 grains.

The amount of gunpowder in a cartridge is also measured in grains. The weight of the gunpowder can affect the performance of the bullet, such as its velocity and trajectory. Different calibers and types of ammunition will have different grain weights of gunpowder.

Choosing the right grain weight for a bullet can impact the accuracy, velocity, and performance of the ammunition. It is important to consider the intended use of the ammunition and the characteristics of the firearm when selecting the appropriate grain weight.
