Equivelent to the CCI 250 Large Rifle Magnum, Federal 215 Large Rifle Magnum, and Winchester Large Rifle Magnum (WLRM) primer.

These are designed for large-capacity, high-pressure, magnum-caliber cartridges (e.g., .300 Win Mag, 7mm Rem Mag) to ensure consistent ignition of slow-burning powder, often in cold weather.

This is a better primer for cold weather than the CCI 250 or Federal 215. Thus, mostly for hunting ammo.

Must be 21 and sold to persons who are federally prohibited from possessing firearms or ammunition (for example, felons, people under certain restraining orders, etc.).
