CCI Small Rifle Magnum Primers #450

Looking for CCI Small Rifle Magnum primers? Some loads demand more aggressive ignition than a standard small rifle primer can deliver — slower-burning powders, cold weather conditions, and certain magnum small rifle cartridges all benefit from the extra flame and longer burn the #450 provides. CCI primers are continuously tested and improved, and today’s formulations are more sensitive, easier to seat, and more compatible with progressive and automated loading equipment than ever before.

Each #450 primer uses a modern, non-corrosive and non-mercuric initiator mix for the cleanest possible burn, giving reloaders the confidence that comes with consistent, reliable ignition even under demanding conditions. It’s the primer your load data will typically call for when a slower-burning propellant needs that extra push to ignite fully and consistently, shot after shot. As always, cross-reference your specific magnum load with CCI’s official reloading data before loading.

If your cartridge doesn’t specifically call for the extra magnum energy, our standard CCI Small Rifle 5.56mm NATO-Spec Military Primers #41 or the everyday #400 may be the better, more economical fit.
