Re: How is military brass crimped?
Welcome to TFF Larrymac1, there are two common ways in which primers are crimped. Most common is a circular ring crimp and the other is a staked crimp. The ring crimp is applied by a crimping die and the staked crimp is applied by "poking" the brass around the primer with two or three prongs that force the primer cup tightly around the primer.
