CCI Small Rifle 5.56mm NATO-Spec Military Primers #41 Box of 1000 (10 Trays of 100)

CCI small Rifle 5.56mm NATO-Spec Military  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.

Number 41 Mil-spec primers are made to the same specifications as 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.

CCI 450 Small Rifle Magnum primers are used for heavier charges of hard-to-ignite powders. Additional differences include composition of the priming mixture, cup thickness, sensitivity and a slight variation in height.

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.
