Packaged in the innovative Advanced Primer System (APS) strips, these 1,000 primers are protected from handling contamination and physical variance from factory to press. Featuring a harder brass cup for high-pressure cartridges (like 6mm BR, 6.5 Creedmoor, and .223 Rem) and a meticulously calibrated clean-burning compound, the BR4 primer minimizes velocity extreme spread and vertical dispersion.

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.
