cci 250 primers (CCI Primers) are continuously tested and improved. As a result today’s CCI primers are more sensitive, easier to seat and more compatible with progressive and automated loading equipment than ever before. They utilize modern non-corrosive and non-mercuric initiator mixes for the cleanest burn possible
Professor Bob From Jackson, NJ –
Back to CCI.. purchased 1000 Remington Magnum large rifle primers for a new Model 70 and thought there was a problem with the rifle! Bought CoreLokts to break in the barrel….Jeez… 4 of 20 would not fire! Called Winchester and tech asked if I was using CoreLokts. He said before I send rifle back, try another brand. I like reloading my own and the CCIs have all fired….over 50 at this point. Remington was very gracious and treated me right. They tested 20 I returned and they all fired. Still scratching my head…. hope this helps others.
