Weatherby’s Hammer Custom line (part no. M300195HCB) loads this .300 Weatherby Magnum round with a 195-grain solid copper monolithic bullet from Hammer Bullets, a design built around high velocity and hydraulic shock rather than classic mushroom expansion. Weatherby developed .300 Weatherby Magnum as one of the hardest-hitting standard-production magnum cartridges available, and 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 serious big-game hunting load.
