Our Approach

We Do Ballistics Better

Weatherby was founded in 1945 by Roy Weatherby, who believed cartridges could deliver more velocity, flatter trajectories, and more decisive terminal performance.

That same ballistic obsession still drives us today. From iconic Weatherby magnums to modern hunting loads, we build ammunition for hunters who expect premium performance, consistency, and confidence in every shot.
