The CCI 200 Large Rifle Primers is a pack of 1000 percussion caps used to reload standard large rifle cartridges. CCI Primers utilise non-corrosive and non-mercuric initiator mixes selected for their clean burning characteristics. All CCI Primers have a larger anvil area to compensate for firearms that may have an off-centre firing pin and are engineered to enable smooth feeding in automated reloading equipment.
