Weatherby’s Hammer Custom line (part no. M65RPM124HCB) loads this 6.5 Weatherby RPM round with a 124-grain solid copper monolithic bullet from Hammer Bullets, a design built around high velocity and hydraulic shock rather than classic mushroom expansion. Weatherby chambers this in the 6.5 Wby RPM, a modern rebated-rim magnum built to fit a standard-length action while delivering magnum-class velocity. Hammer’s fluted nose design is engineered to transfer energy violently on impact, generating a large temporary wound cavity without relying on the bullet mushrooming. In rifle ammunition built around that high-velocity philosophy, this is a specialized hunting load.

Frequently Asked Questions

Does the Hammer Custom bullet expand like a traditional soft point? No, it’s a solid monolithic copper bullet that relies on high velocity and a fluted nose to generate hydraulic shock rather than mushrooming like a conventional expanding bullet.

What makes 6.5 Wby RPM different from other 6.5 magnums? It’s a rebated-rim design specifically built to fit a standard-length action while still delivering magnum-class velocity, rather than requiring a longer magnum action.
