Bullet Seating Depth

Bullet seating depth refers to how far the bullet is placed into the cartridge case when loaded into a firearm. It is measured from the back of the cartridge to the point where the bullet contacts the case neck or jammed into the case. Proper seating depth influences accuracy, bullet stability, and pressure within the gun. If seated too deep, it can cause high pressure or feeding issues; too shallow, and it may affect accuracy or cause instability during firing. Adjusting seating depth is a key part of customizing ammunition for optimal performance based on the firearm and projectile type.
