Weatherby has long been synonymous with high-velocity magnum cartridges, but this model represents a modern evolution of both company and cartridge, blending innovative design with practical field utility.
Let’s start with the 7mm Backcountry cartridge, as it’s central to what makes this rifle special. Developed by Federal Premium after several years of research, the round emerged primarily to meet demands for enhanced performance in compact, suppressor-friendly setups. Hunters increasingly favor shorter barrels for maneuverability in dense terrain or when using suppressors, yet they still want magnum-level ballistics—flat trajectories, high energy on target, and the ability to push heavy bullets at impressive velocities. Traditional brass-cased 7mm cartridges, such as the 7mm Remington Magnum or 7mm PRC, deliver strong performance but often require longer barrels (24 inches or more) to reach peak speeds, and their pressure limits (typically around 65,000 psi) prohibit further gains without added pressures, recoil or bulk. Federal addressed these limitations by introducing a proprietary high-strength steel alloy case called Peak Alloy. This metal is similar in durability to materials that are used in nuclear reactors, race cars, and things like bank vaults. Unlike conventional brass cases, which expand and deform under extreme pressure, Peak Alloy enables a safe operation at up to 80,000 psi. (WOW). This allows the 7BC to achieve velocities around 3,000 fps with 170- to 175-grain bullets from a 20-inch barrel—outpacing many brass-cased equivalents in even full-length configurations—all while maintaining manageable recoil comparable to or slightly less than a 7mm PRC or Rem Mag. The cartridge is dimensionally similar to the .280 Ackley Improved or other cartridges spawned from the .30-06 family, fitting standard long actions and often providing an extra round in the magazine compared to something like the PRCs. It excels with heavy-for-caliber, high-BC projectiles for superior downrange performance, making it ideal for elk, mule deer, or other big game at extended ranges.
Reloading Capabilities
While reloading steel cases can present challenges (different resizing needs and potential corrosion concerns with certain finishes), Federal has now published a selection of recipes for handloaders utilizing LEE reloading dies- currently the only manufacturer to offer them. Factory loads from Federal deliver consistent, high-velocity results optimized for this pressure regime.
Why “307?”
The name “307” pays homage to the area code for all of the state of Wyoming. With a state population of still less than one million people, that area code likely still has some time before it’s full!
Technical Specs
This rifle builds on Weatherby’s newest action platform, the 307, which draws inspiration from the Remington 700 footprint for broad compatibility with aftermarket parts. This two-lug bolt features a smooth 90-degree throw, an M16-style extractor for reliable function, and a plunger ejector. One standout element is the tool-less bolt disassembly: simply push the shroud and pull the handle to remove the firing pin assembly for easy field cleaning. (A HUGE advantage in the field!) The externally adjustable TriggerTech Field trigger breaks crisply,typically around 2.5–3 pounds, and the two-position safety is intuitively placed. A hinged floorplate magazine holds 4+1 rounds in 7mm Backcountry, keeping the profile slim and lightweight. This rifle also includes a pre-installed Peak 44 20-MOA Picatinny rail with 8-40 screws for secure optic mounting, and the muzzle is threaded with Weatherby’s Accubrake DST—a directional, self-timing brake that reduces felt recoil and muzzle rise.
Ergonomically, the Alpine CT feels intuitive right out of the box. The Peak 44 Bastion carbon-fiber stock, weighing just 24 ounces, features a hand-painted sponge pattern in earthy tones (WYO brown and backpack brush accents) that provides decent grip in wet or gloved hands. The forend is flat-bottomed for stable bipod or bag support with dual swivel studs pre-installed while the vertical pistol grip fills the hand comfortably without excess bulk. Length of pull measures a standard 13.5 inches, and the raised comb ensures consistent cheek weld with modern scopes (no need for add-on comb-raisers). The proprietary 3D-Hex recoil pad does a good job absorbing recoil, especially paired with the muzzle brake and the cartridge’s relatively tame impulse. Bolt operation is smooth and effortless, with an oversized knob that’s easy to manipulate and the overall layout promotes natural shouldering and quick target acquisition.
At 6.0 to 6.3 pounds un-scoped (around 6.2 pounds in 7BC), the Alpine CT excels in weight and handling for any pursuits. The balance point sits near the action, giving it a lively yet stable feel—quick to swing for opportunistic shots yet steady when braced. Add a quality scope and you’re still well under 8 pounds loaded, a significant advantage when covering steep ground or glassing for hours.
In practical use, it carries like a much lighter rig than its capabilities suggest, making long days in the field far less tiring. The carbon-fiber barrel is a highlight, produced by BSF with a 416R stainless steel core wrapped under tension. This design creates air gaps around 95% of the barrel surface, promoting faster cooling and vibration damping for consistent accuracy as the barrel heats. The 1:8 twist stabilizes heavy 7mm bullets effectively, and Weatherby guarantees sub-MOA performance (often tighter in testing). In the 7mm Backcountry chambering, the barrel is typically 20–22 inches (plus the brake), optimizing velocity without excess length or weight. The tensioned wrap helps maintain harmonics, contributing to reliable groups even after strings of fire—crucial in hunting scenarios where follow-up shots matter. What sets the Model 307 Alpine CT apart from Weatherby’s other rifles is its departure from the proprietary Mark V action (with its nine-lug, high-pressure design for classic Weatherby magnums) and the more traditional Vanguard. The 307 introduces Remington 700 compatibility, opening up extensive aftermarket options for stocks, triggers, and accessories. The Alpine CT variant emphasizes ultralight construction with full carbon components (stock and barrel), contrasting with heavier Mark V Backcountry models or those with titanium accents. Priced around $2,200–$2,250, it delivers premium features at a more “accessible” level than fully custom builds. While Mark V rifles may still remain the go-to for exotic magnum performance, the 307 line appeals to hunters seeking modularity, reduced weight, and crossover appeal between precision and field use.
Range Test
For this test, I chose to mount a Steiner Predator 4S short rifle scope in 4–16 X44 mm configuration. After all, if you’re going to shave pounds and inches off of a rifle to save weight, it certainly doesn’t make sense to throw a 3+ pound scope on it! Since I am not a “long range” Hunter (less than 400 yards for most shots), 16 X is plenty of magnification. I also shot both with and without an anechoic titanium suppressor installed. Surprisingly, the rifle was close to dead on with use of a magnetic bore sighter.
One thing I noticed immediately was that in the first several rounds of shooting, two of my target holes would be touching, with one off 3/4 to 1 inch. This is common with lightweight, carbon barrels as they can heat up fast under heavy shooting. A five minute cooldown between each shot made all groups closer. Additionally, I was shooting at my “desert range,” and my folding table shooting bench is nowhere near as stable as the benches at my home range.
Recoil is more than manageable and can only be described as feeling a bit “odd.” When you’ve fired hundreds of different rifles in dozens of different calibers, you get a feel for what every shot should feel like. The 7 BC is different. Not bad – just different.
Not surprisingly, shooting with the suppressor installed was much more pleasant. Musel breaks do a good job mitigating recoil, but they are LOUD.
