“10mm auto”

If the .338 Winchester Magnum puts an exclamation point on the end of the hunting sentence, the .340 Weatherby Magnum highlights and italicizes the paragraph. After all, that’s what the Weatherby cartridges were designed to do, and the .340 Weatherby does it well.

Introduced in 2008, the .416 Ruger is the only commercially produced cartridge in that .416-inch bore diameter designed to fit in a long-action receiver, making it an ideal choice for dangerous game.

Nosler took the venerable .270 caliber to a new level with the introduction of the 27 Nosler. Conceived as a 21^st century upgrade, the cartridge delivers previously unobtainable downrange ballistics by pairing the ultimate combination of case capacity with modern long-for-caliber bullets.

The .257 Bob certainly has lost popularity of late, but those who still take him afield each fall quietly go about their business, accurately placing shots and taking game without destroying any more meat than is necessary.

Introduced in the mid-1940s, the 7mm Weatherby Magnum case has minimal taper, maximizing powder capacity, and the correlative muzzle velocities show Roy Weatherby’s penchant for speed. Anything the popular 7mm Rem. Mag. will do, the 7mm Weatherby will do just a bit faster.

A beltless non-rebated .30-caliber magnum rifle cartridge designed for extreme performance at long range, the .300 PRC is the product of years of tinkering by Hornady. It will handle almost any game in North America and is fully capable of doing double duty as a long-range target choice.

The .350 Rigby Magnum is vastly overlooked even among rifle cranks but was at one time as popular as the .375 H&H Magnum. Released in 1908, it is an entirely original design, and was the first to feature the sharp 45-degree shoulder which is the hallmark of the Rigby designs.

Despite its rarity today, we all owe the .450 Nitro Express a debt of gratitude for the simple fact that it established a ballistic formula upon which so many dangerous game hunters rely.

The .17 Hornet, son of the classic .22 Hornet, is a well-balanced design. Sharing the rimmed design of the parent case, it feeds nicely in a bolt-action repeating rifle, provides pinpoint accuracy and minimal recoil, and checks all the boxes for varmint hunting.
