CCI makes two shotshell primers to cover your needs. CCI 209 primers are for field and target loads in all gauges. This primer is a general purpose shotshell primer for most field and target loads. The CCI 209M (Natchez item CC0009) is a true Magnum primer designed for heavy charges of slow-burning propellants. That makes the 209M a superb choice for waterfowl loads. Both use modern, non-corrosive, non-mercuric primer compounds for clean, sure ignition.
