A proven performer, CCI® standard primers deliver trustworthy performance for home reloaders. Easier to seat than older-style primers, CCI standard primers feed more smoothly in today's progressive and automated loading equipment. With its clean-burning initiator compound, these non-corrosive, non-mercuric primers deliver a clean burn to leave primer pockets cleaner for greater accuracy and more shots between cleanings. The increased sensitivity design also provides a larger ''sweet spot'' for better use with guns that sometimes deliver off-center strikes.
