CCI Small Pistol Primers For Sale. CCI Primers undergo ongoing testing and enhancement. Consequently, CCI primers of today are more sensitive, simpler to seat, and compatible with progressive and automated loading equipment than ever before. Modern non-corrosive and mercury-free initiator mixtures are used for the cleanest possible burn. These are the most usually called-for primers in reloading recipes, the “bread and butter” of the reloading industry. Standard primers from CCI burn very cleanly, leaving primer pockets cleaner and lengthening the duration between cleanings.
