Weatherby .300 Weatherby Magnum 165gr Hornady Interlock SP Ammunition /20

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. We anticipate the stories ahead: the successful harvests, the superb accuracy, and the relationships formed around the fire ring. Hopefully, you will choose a Weatherby rifle and ammunition to accompany the journey, and create memories forged for a lifetime.

By far the most popular and versatile Weatherby cartridge available. The 300 Weatherby Magnum had the flattest trajectory, longest range and the greatest killing power of any 300 magnum on the market until the 30-378 Weatherby Magnum came along. Based on the 300 H&H Magnum, the 300 Weatherby delivers 300 more fps than its British cousin. Introduced in 1944, this is the all-around cartridge for the big game hunter.

About the Manufacturer



The history of Weatherby began in the mid-1940s when a young cartridge "wildcatter" named Roy Weatherby set out to change the world of firearm performance. Contrary to then-popular thinking (heavy bullets pushed at slow speeds), Roy believed that lightweight bullets traveling at super high speeds provided the best combination for one-shot kills. Based upon that philosophy, he spent the next decade developing the high-powered Weatherby Magnum cartridges for which the company is known today (.224, .240, .257, .270, 7mm, .300, .30-378, .340, .338-378, .375, .378, .416 and .460).

Throughout that period, Roy was also producing or re-chambering rifles designed specifically to accommodate his super-charged ammunition. At that time, he was producing his rifles on FN Mauser and French Brevex Magnum Mauser actions. However in 1957, Roy would again catch the attention of the shooting and hunting world with a proprietary action that is today recognized around the world as the Mark V.

The foundation for the Mark V was the need for a stronger, safer action, able to withstand tremendous pressure, and the possibility of blown primers and ruptured case heads (due to the unpredictability of early handloaded and wildcat cartridges). After nearly a half century of proven performance, the Mark V continues to be known as the world's strongest bolt action.

In 1970, Roy once again showed his entrepreneurial spirit when he introduced the Weatherby Vanguard action, borrowing many of the same characteristics and design elements of the Mark V with two locking lugs (vs. 9 in the Mark V).

The Weatherby lineage continued in 1983 when Roy's son, Ed Weatherby, assumed the leadership mantle of the company. Under Ed's guidance, the company has seen growth and expansion both in Mark V and Vanguard offerings, including the newest Vanguard rifles, which feature guaranteed SUB-MOA accuracy. In addition to rifles, we offer a full line of Semi-Automatic and Pump shotguns, as well as accessories, apparel and collectibles.

The innovation and pacesetting performance associated with the Weatherby name spans 70 years. Yet, while our place in history is firmly established, it is the prospects for the future that shine brightest of all.
