“6.5-300 weatherby”

Roy Weatherby was the godfather of the “speed kills” mantra, and so he designed his rifle cartridges to be the fastest and therefore the hardest hitting. Over 70 years later, the company is, er, sticking to its guns with the release of what is the fastest production 6.5-caliber cartridge, the new 6.5-300 Weatherby Magnum. Here are five things you need to know.

The 26 Nosler and 6.5-300 Weatherby Magnum are some of the fastest cartridges in their class, and both are extremely accurate, so which is the better choice for hunters?

A one-of-a-kind Weatherby Mark V, hand-engraved in combined recognition of Weatherby's 70th Anniversary, the introduction of the new Model Mark V and the introduction of the new 6.5-300 Weatherby Magnum cartridge, will be featured in the SHOT Show 2017 auction.

Weatherby will deliver its first new cartridge in nearly 20 years in 2016, with the introduction of the new 6.5-300 Weatherby Magnum. The impending release is already being hailed as the fastest 6.5mm production cartridge in the world.

Many a Weatherby caliber has been celebrated, maligned and at times surpassed. But none can be called insufficient for the job. Today, 71 years after the company’s founding, with the introduction of the 6.5-300 Weatherby Magnum, the company again claims the high ground.

Weatherby’s flagship rifle is now available in two new versions built specifically with backcountry hunters in mind.

The addition of a carbon fiber barrel rounds out the Mark V’s recent re-freshening and ensures that the Flying W brand’s flagship firearm is still one of the “it” rifles in the world of long-range hunting.

The 6.5mm craze shows no signs of slowing down; in fact, it’s looking to be the bore diameter of the 21st century. Which of these two new cartridges is the better choice for the hunter? Contributor Philip Massaro examines the pros and cons of each.

The goal was to build a magnum-class cartridge in a small package, and Weatherby has done just that with its 6.5 Weatherby RPM, featuring a rebated rim, large body diameter, low body taper and 35-degree shoulder.
