Primers #300
CCI Primers #300 are continually tested and improved. As a result, CCI primers #300 are more sensitive, easier to seat, and compatible with progressive and automated loading equipment than ever before. They use modern non-corrosive and non-mercuric initiator mixes to achieve the cleanest burn possible. There are 1000 and 5000 count boxes available.
