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.
