Weatherby 307 Alpine St 280Ai 22 Brake

The Weatherby 307 Alpine ST in .280 AI with 22" brake is a purpose-built rifle that marries modern lightweight engineering with serious field capability. Built on Weatherby's new Model 307 bolt-action platform, this is a two-lug fully cylindrical action designed from the ground up for compatibility with today's vast ecosystem of aftermarket stocks, triggers, rails, and mounts—giving you flexibility most factory rifles simply don't offer. Partnered with PEAK 44, the Alpine ST delivers an ultralight platform without compromising on accuracy or durability.

What makes this rifle stand out is how it balances weight with performance. The PEAK 44 Bastion stock tips the scales at just 24 ounces and incorporates a proprietary 3D-Hex recoil pad designed to absorb punishment—critical in a rifle chambered in .280 AI, a cartridge known for its velocity and power. The barrel is spiral fluted for rigidity and light weight, while the included Accubrake ST muzzle brake works to further manage recoil, letting you stay on target through follow-up shots and maintain better control in the field.

Aesthetically, the Alpine ST turns heads too. The receiver, barrel, and brake are finished in Graphite Black Cerakote, while the bolt and knob match for a cohesive look. The stock features exposed carbon fiber with grey and gold brushed sponge accents—aggressive yet refined. This isn't a rifle designed to disappear into the truck; it's built to perform and look the part doing it.

The .280 AI chambering offers hunters and long-range shooters a balanced option: flat trajectory, excellent downrange energy, and manageable recoil—especially in a platform this efficient. Whether you're heading into alpine country where weight matters, setting up at the range, or hunting medium to large game, the 307 Alpine ST delivers accuracy and control without the fatigue that comes with carrying heavier setups all day.

Is the .280 Ackley Improved a good choice for hunting and long-range shooting?

The .280 AI is a proven cartridge for hunters and long-range shooters. It offers a flat trajectory, solid downrange energy on game, and manageable recoil—especially in a lightweight platform like the Alpine ST. The .280 AI splits the difference between ballistics and shootability, making it versatile for a range of hunting scenarios and target work.

The PEAK 44 Bastion stock alone weighs just 24 ounces. The spiral fluted barrel is designed to be lightweight without sacrificing rigidity.
