Primers are small metal-clad cups that hold priming mixture, an anvil, and a foiling disc. Primers fit into the case’s primer pocket, creating a spark when hit with the firing pin.

The case must be primed before adding new powder, so that your gun’s propellant powder can be contained at the bottom of the case.
First, check to make certain you have the right size. Primers for U.S. cartridges come in two diameters — large (0.210”) and small (0.175”) — and two general types — rifle and pistol. Rifle primers have more rigid cups and a hotter flash than pistol primers.
WARNING – Always store primers in their original, compartmentalized packaging. Handle them with care and respect. Primers that touch each other are more dangerous than single primers.
As you become more proficient in reloading, you will fine-tune your own process based on your tools/equipment, the type of shooting you do, the guns you reload for and the goals you have for your handloaded ammunition. We suggest that you continue to read, learn and understand various methods so that you can find the system that works best for your needs.
SAFETY – Please follow all pertinent safety procedures such as wearing safety glasses and hearing protection, being in a well-lit and well-ventilated workspace, and having all reloading tools in top working condition and no flames, sparks or static electricity.
