Ultra-high velocity, magnum ammunition is how Roy Weatherby got started in the 1940s. As a young wildcatter, he revolutionized the industry with his fast, hard-hitting loads that were dead-on accurate. Today, those same performance qualities are every bit a part of Weatherby cartridges.

Weatherby’s move to Wyoming is an exciting step towards continual opportunity for innovation. The cartridges that paved the way for advancement in ballistics and load development will forever be a solid foundation. Weatherby’s intention is constant progression for ballistic superiority, confident in developing new and impressive cartridges that perform and meet expectations attached to the Weatherby brand.
