Weatherby Select 338 Weatherby RPM 225gr Hornady InterLock - 20RDS

The 338 WBY RPM (Rebated Precision Magnum) is based on the Weatherby 6.5 RPM necked up to accept a 338 caliber bullet. Introduced in 2022 the 338 RPM was designed to take advantage of Weatherby 6-Lug action to get magnum performance in a 5lb rifle. The large body diameter, low body taper, and 35-degree shoulder mean that case capacity is greatly increased, leading to higher velocities.

The Hornady InterLock® features an exposed lead tip for controlled expansion and hard-hitting terminal performance. A secant ogive design — one of the most ballistically efficient profiles ever developed. The raised ring inside the jacket is embedded in the bullet, combined with the one-piece core, keeps the core and jacket locked together during expansion to retain mass and energy.
