Weatherby Ammo 300WBY 195gr Hammer Custom, 20 Rounds/Box, 10 Boxes/Case

The Weatherby Ammo 300WBY Magnum in 195-grain Hammer Custom is a premium hunting round engineered for serious big-game pursuit. Since its introduction in 1945, the 300 Weatherby Magnum established itself as a hard-hitting, versatile .30 caliber option capable of taking down larger game at extended ranges. This particular load pairs the proven cartridge with a 195-grain Hammer Custom bullet, combining the speed and energy the magnum is known for with modern bullet construction designed for controlled expansion and deep penetration on game. Whether you're pursuing elk across open country or setting up for long-range hunting in varied conditions, this ammunition delivers the velocity and stopping power the 300 WBY was built to provide.

Weatherby's factory ammo comes in convenient 20-round boxes, and this case includes 10 boxes (200 rounds total), making it practical for hunters who shoot enough to stock reliable, tested ammunition rather than sorting through components or loading their own. The 195-grain bullet weight sits in the mid-to-heavy range for the cartridge, balancing trajectory with the kinetic energy needed for ethical, effective kills on large game. If you shoot a 300 Weatherby and want ammunition you can trust without guesswork, factory loads like this remove variables and let you focus on shot placement.

300 Weatherby ammo isn't stocked everywhere, so having a known source matters. This is purpose-built ammunition for a purpose-built magnum, not a generic substitute. If you've already invested in a Weatherby Mark V or another 300 WBY rifle, you know the cartridge's reputation. This load respects it.
