In the realm of firearms, where precision meets power, Weatherby has introduced a formidable contender: the 338 WBY RPM. Launched in 2022, this cartridge exemplifies engineering prowess by harnessing magnum capabilities within the confines of a lightweight platform. Specifically designed for use with the Mark V 6 Lug action, it offers hunters an unrivaled tool to pursue all of North America's big game.
The essence of the 338 WBY RPM lies in its construction. Crafted from the foundation of its predecessor—the 6.5 RPM—this round has been expertly necked up to accommodate a robust .338 caliber bullet. This transformation is not merely cosmetic; it serves a tactical purpose by optimizing performance without sacrificing portability or agility.
A key feature that sets this cartridge apart is its case design: characterized by a large body diameter and minimal taper paired with a pronounced 35-degree shoulder angle. This configuration significantly enhances powder capacity, which translates directly into higher muzzle velocities—a crucial factor when engaging distant targets with authority and accuracy.
For those who venture into backcountry terrains demanding both dependability and stopping power, the 338 WBY RPM represents more than just an option—it stands as an invitation to expand one’s hunting horizons while wielding unmatched ballistic efficiency.
