Weatherby Ammo 6.5-300WBY 129gr Hammer Custom - 20 Rounds/Box

The Weatherby Ammo 6.5-300WBY with 129-grain Hammer Custom bullets delivers serious velocity and precision in one of the fastest 6.5mm cartridges available. Built on the 300 Weatherby Magnum case necked down to 6.5mm, this round combines the case capacity and pressure characteristics that made Weatherby famous with the ballistic efficiency and accuracy potential of modern 6.5mm projectiles. Whether you're pushing the limits at long range or hunting medium to large game, this factory load puts consistent, hard-hitting rounds downrange.

Weatherby's 6.5-300WBY bridges the gap between magnum power and 6.5mm precision. The 129-grain Hammer Custom bullet is engineered for controlled expansion and deep penetration, giving you a cartridge that doesn't waste case capacity on unnecessary velocity while sacrificing accuracy. This is serious long-range ammunition for shooters who've already committed to a 6.5-300WBY rifle and want to trust their factory loads for hunting, competition, or range work.

Each box contains 20 rounds of Weatherby factory ammunition, so you're getting ammo built to the exacting standards of the parent company—the folks who designed the cartridge itself. That consistency matters when you're dialing in a precision rifle or depending on your load in the field.
