Loosely based on a shortened .404 Jeffery case with the rim rebated to the .535-inch case head of the H&H family, the .270 WSM was the third commercial cartridge using the .277-inch bore diameter, and betters the velocity of the .270 Winchester by 200 to 250 fps.

Fulfillment of a 40-year dream delivers a flood of good vibes.

Remington’s new 360 Buckhammer straight-wall cartridge is optimized for lever-action rifles, deadly and accurate out to 200-plus yards.

If you’re a velocity hound, the 30 Nosler is among the fastest .30-caliber cartridges housed in a long-action receiver.

Developed in 1976 by Ken Waters as a wildcat cartridge, the 7-30 Waters is based on the .30-30 Winchester necked down to 7mm to improve velocity and trajectory, with a significant drop off in felt recoil. In 1984, Winchester began to produce rifles chambered for cartridge, legitimizing Waters’ dream, and establishing it as a commercial cartridge.

In 2003, Finnish firearms manufacturer Sako released its own variant of the 9.3mm rimless cartridge: the 9.3x66mm Sako, or as it is known in the U.S., the .370 Sako Magnum. It delivers performance on par with the beloved .375 H&H in a package which can hold one additional round in the magazine in a lighter rifle.

Hornady’s dive into a .17-caliber rimfire was met with fanfare, as it truly was—and still is—a decided improvement over the long-range ballistics of any of the .22 rimfire cartridges.

For 2023, Taurus introduces its Raging Hunter .460 S&W Magnum, featuring a 10.5-inch barrel with a proprietary compensator that drastically tames recoil, and a bottom rail for attaching stabilizing devices like bipods or shooting sticks.

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.
