Large Rifle Magnum Primers

Large rifle magnum primers are used in some of the most powerful big game loads out there--the .375 H&H Magnum, the .338 Lapua, the .300 Weatherby Magnum, and the various Winchester magnums.

Since they are more powerful than standard primers, Large Rifle Magnum primers are ideal for large capacity cases and for shooting with ball powders or in cold weather.

Winchester, CCI, and Sellier & Bellot are some of the notable manufacturers of LRM primers.

    CCI #250 primers are a top choice for loading big bore magnum rifle cartridges. CCI's primer designs are trusted by top manufacturers of commercial and military munitions due to a non-corrosive, sensitive mixture combined with an enlarged strike zone which contribute to reliability. In addition, these primers have been constantly tested and improved over time for optimal fit and compatibility with the widest range of reloading tools.

    These large rifle magnum primers emit a longer-lasting flame that burns with a 23% increase in temperature over the standard large rifle type; this ensures full ignition of slow burning propellant, even with spherical grains, in large capacity casings. CCI Magnum primers are also very resilient to the elements and will ignite in extremely cold temperatures.
