Large and Small Primers in Stock

If you're in search of an array of primers in stock, you've come to the right place. We carry primers for the most popular sizes of ammunition reloads. Our brands vary based on availability but can include Winchester, CCI, and Remington. Our website will guide you to all the rifle and pistol primer sizes available to suit all types of ammunition.

A primer is a small metal cap, that holds a small quantity of explosive chemicals which ignite when it is smashed between the cap and the anvil in the cartridge. This ignition of the primer then ignites the gunpowder, causing an explosion and propelling the bullet down the barrel of your weapon. Matching the right primer to your propellant choice is key, and with our wide array of in-stock primers, we make it easier to get the right one.

We can help you with the right primer to compliment your favorite cartridge and powder preferences.

Small Rifle Primers

Small rifle primers come standard with a diameter of .175 inches. This style of primer may look similar to a small pistol primer, but don't use them interchangeably. The primers are filled with the right compound to create the correct powder burn needed to achieve the muzzle velocity you need for your small rifle.

Whether you need CCI or Fiocchi, we have these and several other brands that manufacture small rifle calibers. You can sometimes find these primers where you buy guns online. At The Castle Arms, we are the go-to online resource for purchasing reloading parts.

Large Pistol Primers

Large pistol primers are known to possess more propellant in order to create a clean burn of the larger quantity of gunpowder in order to deliver enough velocity for the large caliber bullets since they are heavier. Serving larger weapons with a .210 inch diameter, they may look similar to large rifle primers, but they are not interchangeable.

Always buy the right primers to ensure you don't end up with too much or too little force for your weapon. This is also why brands come with so many different families of primer, to meet all types of ammunition needs.

CCI Primers

CCI primers are a primer manufacturer with a well-vetted reputation for manufacturing reliable primers. They make several sizes with tight specifications to fit every primer need. They offer small rifle primers, large pistol primers, and even offer primers for muzzle-loading firearms.

CCI primers are reliable and can be purchased in match-grade as well as standard. With CCI, their match-grade primers have a bit of a thicker cup compared to the standard, which helps to support a load that might be a bit hotter than with a standard-style primer. The match-grade primers in stock pass through stricter quality assurances and are more reliable for more consistent delivery of the projectile downrange.
