The CCI 350 Large Pistol Primers is a pack of 1000 percussion caps used to reload magnum large pistol cartridges. Magnum primers are intended for large-capacity cases, very low temperatures and/or ball propellants.
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.
