Description
There is something about a walnut-stocked Weatherby that just looks right in a gun rack, and the 307 Adventure SD nails that classic feel without living in the past. The fancy walnut stock wears a rosewood forend tip and grip cap with a maple diamond inlay and spacers, shaped into the Monte Carlo profile Weatherby made famous. That comb design is not just for show either. It was drawn up to redirect recoil away from your cheek, which matters when you are pushing a barrel-burner like the .257 Weatherby Magnum.
The Model 307 Action Under the Hood
Underneath the pretty wood sits Weatherby's first new action in over 50 years, built in Sheridan, Wyoming. The Model 307 is a two-lug, fully cylindrical design with a Remington 700 pattern footprint, so it plays nice with a huge range of aftermarket stocks, triggers, rails, and bottom metals if you ever want to tinker. The three-piece bolt breaks down without tools for easy cleaning in camp, and an M16-style extractor with a plunger ejector keeps cases moving reliably. A crisp, externally adjustable TriggerTech Field trigger comes standard, along with a two-position safety and a traditional hinged floorplate.
Built for the .257 Weatherby Magnum
The .257 Wby Mag is one of the flattest-shooting big game cartridges ever loaded, and this rifle gives it room to run with a 26 inch fluted, threaded barrel topped by Weatherby's Accubrake to tame muzzle jump. Barrel, receiver, and bolt are all coated in Graphite Black Cerakote, so the metalwork shrugs off weather that would have you babying an old blued rifle. There are no iron sights, but the receiver is drilled and tapped so you can mount the glass this cartridge deserves.
Why the Adventure SD Earns a Spot in the Safe
Every rifle built on the 307 action carries Weatherby's sub-MOA guarantee, a three-shot group of .99 inch or better at 100 yards from a cold barrel with Weatherby factory or premium ammo. That is custom-shop confidence in a rifle that looks like it belongs over the fireplace and hunts like it belongs on the mountain.

Frequently Asked Questions
Does the Weatherby 307 Adventure SD come with sights or a scope?
No, this rifle ships without sights or optics. The receiver is drilled and tapped for scope mounts, and since the 307 action shares the Remington 700 footprint, finding compatible bases and rings is easy. Given how flat the .257 Weatherby Magnum shoots, a quality scope is the way to go.
Is the Model 307 action compatible with Remington 700 accessories?
For the most part, yes. The 307 is a fully cylindrical, two-lug action with a 700-pattern footprint, so it works with a wide range of aftermarket stocks, triggers, rails, and bottom metals. It is the most open platform in Weatherby's lineup, though it is its own action with upgrades like tool-less bolt disassembly and an M16-style extractor.
How bad is the recoil on the .257 Weatherby Magnum version?
It is more manageable than you might expect. The factory Accubrake takes a big bite out of felt recoil, and the Monte Carlo stock design directs recoil away from your face. Between the brake, the stock geometry, and the rifle's weight, the .257 Wby Mag is pleasant to shoot for a magnum cartridge.
Does the 307 Adventure SD have an accuracy guarantee?
Yes. Weatherby guarantees a three-shot group of .99 inch or less at 100 yards from a cold barrel when using Weatherby factory or premium ammunition, valid for two years from the verified purchase date for the original purchaser. Independent testing of the Adventure SD has backed up that claim on the range.
