About Reloading Primers:

The first pinfire primer was developed by French gunsmith Casimir Lefaucheaux in 1828. It was followed by the Berdan primer patented in 1866 and the Boxer primer designed almost concurrently. The primer sets the entire firing process in motion.

Primers FAQs:

  1. What is a primer?

A primer is the component of a handgun or rifle that provides the spark that ignites the gun powder. This causes combustion, which pushes the ammo out of the gun barrel.

Some experts describe the primer as a rocket engine or mini volcano that expels burning slag to mix with the gunpowder in the cartridge.

  1. What are the major primer manufacturers in the U.S.?

The major manufacturers of primers in the U.S include:

  • Winchester Ammunition, based in Oxford, Mississippi, and East Alton, Illinois
  • Cascade Cartridge Inc., also known under the abbreviation CCI, based in Lewiston, Idaho
  • Federal Premium Ammunition, based in Anoka, Minnesota
  • Remington Ammunition, based in Lonoke, Arkansas

These top companies supply primers for law and military enforcement as well as civilians.

  1. What are the primers manufactured in the U.S. made of?

The primers manufactured in the U.S. are made of non-corrosive and non-mercuric chemicals. The materials used for primer production include antimony sulfide, lead styphnate and barium nitrate.

  1. What are the most common sizes for primers?

Though primer sizes vary per manufacturer, the most common sizes include:

  • Small rifle primers, which are approximately .120 inches tall and .175 inches in diameter
  • Small pistol primers, which are designed for handguns and are similar in size to small rifle primers

  1. How do I re-prime my cases

To re-prime:

  • First you need to de-prime using a de-priming die or sizing die.
  • Next clean the primer pockets, with various tools available, to remove the carbon buildup.
  • Clean your cases and trim/chamfer if necessary.
  • Now your cases are ready to insert the new primer. This is done by either a handheld, press mounted or bench mounted priming tool. After this step you are ready to measure and load powder.
  1. What should I consider when reloading and handling primers?

When reloading and handling primers, consider the following:

  • Always refer to a loading manual to see which primers to use.
  • Test different primer makes to find the one that offers you the most accuracy
  • Avoid touching the primers with your hands, as oils can affect reliability.
  • Use safety glasses to protect your eyes from possible explosion and injury during priming of cases.
