Reloading dies are special tools that are fixed into the tool head of the press and are specific for each calibre.
There are 6 basic functions of dies: de-priming, sizing, powder charging, expanding, seating and crimping.
The sizing and depriming functions are usually combined in one die, wherethe case is cleared of the old primer and sized to factory dimensions. The sizing is performed either on the entire length of the cartridge case (full length sizing) or just a neck only (collet/neck sizing dies - available only for bottle cases).
The expanding and powdering function is most often combined in pistol calibre dies. The purpose of the expanding function of the die is to create a slight flare on the neck of the brass case to make it easier to seat the bullet. During this operation, the case may also be charged with gunpowder using either attached automatic powder dispenser, or manually through attached powder funnel.
The seating die is used for the accurate seating of the bullet
