CCI Large Rifle Magnum Primers 250 available at SUPREME GUNSHOP. 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.
CCI primers are highly evolved products because they are continuously tested and improved. Today’s CCI primer is more sensitive, easier to seat, and more compatible with progressive and automated loading equipment than even before.
CCI primers have always incorporated modern non-corrosive and non-mercuric initiator mixes.
