CCI Primers are evaluated and refined throughout time. Because of this, CCI primers available today are more sensitive, simpler to seat, and compatible with progressive and automated loading equipment than ever before. For the cleanest burn possible, they use contemporary non-corrosive and non-mercuric initiator blends. Certain shooting situations in the real world call for a more forceful initiation than what is offered by ordinary primers. A hotter primer flame and a longer burn time are frequently required by large cases, cold conditions, and particular propellants. You receive that advantage with CCI Magnum primers in addition to all the qualities that make CCI primers so wonderful. available in cartons with 1000 or 5000 counts.
