In firearms and artillery, the primer (/ ˈ p r aɪ m ər /) is the chemical and/or device responsible for initiating the propellant combustion that will propel the projectiles out of the gun barrel.
Components of a modern bottleneck rifle cartridge. Top-to-bottom: Copper-jacketed bullet, smokeless powder granules, rimless brass case, Boxer primer.. Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components (metallic/polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded ...
Removing the spent primer from (decapping) these cases requires the use of a special tool because the primer anvil (on which the primer compound is crushed) is an integral part of the case and the case, therefore, does not have a central hole through which a decapping tool can push the primer out from the inside, as is done with Boxer primers.
Source(s): The Handloader's Manual of Cartridge Conversions, by John J. Donnelly, Stoeger Publishing, 1987, ISBN 978-0-88317-269-8. p. 686.

A semi-automatic firearm is a self-loading repeating firearm whose action mechanism automatically loads a following round of cartridge into the chamber and prepares it for subsequent firing, but requires the shooter to manually actuate the trigger in order to discharge each shot.
A self-loading rifle or auto-loading rifle is a rifle with an action using a portion of the energy of each cartridge fired to load another cartridge. Self-loading pistols are similar, but intended to be held and fired by a single hand, while rifles are designed to be held with both hands and fired from the shoulder.
Repeating actions are characterized by reciprocating/rotating components that can move cartridges in and out of battery from an ammunition-holding device (which is a magazine, cylinder, or belt), which allows the gun to hold multiple rounds and shoot repeatedly before needing a manual ammunition reload.
