Weatherby
The Weatherby Ammo .300 WBY 170gr Hammer Custom represents a loaded round built on one of the most enduring magnum cartridges in American hunting—a caliber that's earned its reputation for delivering real velocity and stopping power in the field. Each box contains 20 rounds of factory ammunition loaded with 170-grain Hammer Custom bullets, designed for hunters and shooters who demand consistent, hard-hitting performance across a range of hunting situations. Whether you're stalking elk across high country, glassing open terrain for mule deer, or working through brushy cover where quick, reliable performance matters, this .300 WBY load balances velocity, energy, and practical accuracy in a cartridge that has proven itself for decades.
The .300 WBY is a .30-caliber magnum that's been the go-to for serious hunters since Roy Weatherby introduced it in 1945—long before many of today's popular magnums came to market. The cartridge itself thrives on versatility. It delivers the energy you want for larger game while remaining manageable in recoil-sensitive hunting situations, and it shoots flat enough to make longer-distance field shots more forgiving than smaller-bore alternatives. The 170-grain bullet weight sits in the sweet spot for .300 WBY use: heavy enough for deep penetration and retained energy, but fast enough to take advantage of the cartridge's case capacity.
These are loaded rounds—no reloading, no components to sort. Grab a box, load your magazine or single-loader, and head out the door. Consistency and reliability are what you need when you're counting on ammunition in the moment, and factory loads from Weatherby deliver both. If your rifle is a .300 WBY and you're looking for a proven, hard-working cartridge that won't let you down, this is solid ammunition for hunting and range use.
