The RCBS Seater Die is a specialized reloading die designed to seat the bullet and provide a built-in roll crimper to secure the bullet in place simultaneously ensuring that the bullet is seated to the desired depth and is held securely in place in the casing.
When using a Seater Die you will first insert your brass casing and your bullet into the die. As you raise the ram of your reloading press the die will seat the bullet into the brass casing to the desired depth. At the same time the die applies a roll crimp to the case mouth which helps to hold the bullet firmly in place.
The roll crimp is a type of crimp that rolls the edge of the case mouth into the bullet cannelure to hold the bullet securely in place. This is especially useful for cartridges that will be used in high-pressure applications such as hunting or target shooting.
