CCI Primers are continuously tested and improved. As a result today’s CCI primers are more sensitive, easier to seat and more compatible with progressive and automated loading equipment than ever before. They utilize modern non-corrosive and non-mercuric initiator mixes for the cleanest burn possible. Some real-world shooting conditions require more aggressive initiation than provided by standard primers. Large cases, cold weather, and certain propellants often require a hotter primer flame and a longer burn. CCI Magnum primers offer you that edge, plus you get all the attributes that make all CCI primers so great. Available in 1000 or 5000 count boxes.

They utilize modern non-corrosive and non-mercuric initiator mixes for the cleanest burn possible. These are the “bread-and-butter” of reloading, the most commonly called-for primers in reloading recipes. CCI standard primers are remarkably clean-burning, leaving primer pockets cleaner and extending the time between pocket cleaning. That’s a huge benefit for progressive reloaders. They are more sensitive and easier to seat than older CCI primers, and engineered for smooth feeding in automated equipment. Available in 1000 or 5000 count boxes.

Number 41 Mil-spec primers are made to the same specifications of the U.S. Military and reduce the chances of a slam-fire. While designed for you in Military-style semi-auto rifles, they use the same data as CCI magnum primers.

Note from CCI:

• Effective slam-fire prevention requires more than mil-spec primers. Headspace, chamber condition, firing pin shape and protrusion, bolt velocity, case condition and other factors can affect slam-fire potential.
