Weatherby 307 Range SF 25 WBY RPM 20″ Threaded Barrel
Pros & cons
What works
- Factory 5/8-24 threaded muzzle—ready for suppressor mounting without gunsmithing.
- TriggerTech trigger provides a consistent 3.5 lb. break out of the box.
- Uses standardized AICS-pattern magazines for easy aftermarket sourcing.
- 20-inch Sendero contour barrel provides excellent heat management for 30-40 round strings.
Trade-offs
- Proprietary 25 WBY RPM cartridge limits affordable, off-the-shelf ammo selection.
- 8 lb. weight is substantial for a 20-inch barrel rifle, not ideal for long carries.
- Stock cheek piece requires a 3/32” hex wrench for adjustment—not tool-less.

About this product
The Weatherby 307 Range SF 25 WBY RPM 20″ Threaded Barrel is a modern, modular bolt-action rifle built for long-range precision and suppressor compatibility on a repeatable platform. It’s built on the Model 307 action, which is the core Weatherby designed for aftermarket compatibility with modern stocks, triggers, rails, and AICS-pattern magazines. This specific chambering in 25 WBY RPM with a 20-inch heavy, threaded barrel targets shooters who want factory performance in a compact, adaptable package.
What is the Weatherby 307 Range SF used for?
This rifle is used for precision target shooting, medium-range hunting, and as a suppressor host. The combination of a 20-inch Sendero-contour barrel, a 1:7.5 twist rate optimized for heavy .25-caliber bullets, and a 5/8-24 threaded muzzle gives you a stable platform suitable for sub-MOA groups with proper ammo, and direct compatibility with a wide array of muzzle devices without an adapter.
How does the Weatherby 307 Range SF compare to the Stevens 334 Rifle?
The Weatherby 307 Range SF is a more modular and suppressor-ready platform than the Stevens 334. The Weatherby’s action is designed from the outset to accept modern chassis systems and AICS magazines, while the Stevens uses a more traditional blind magazine. For suppressor use, the Weatherby’s factory-threaded 5/8-24 muzzle is superior—the Stevens 334 in .308 Win would require aftermarket threading, adding about $200 and 2-3 weeks of gunsmith lead time.
What does it weigh and what are the dimensions?
The rifle weighs 8 lbs. (128 oz.) with an overall length of 39.5 inches. The barrel profile is a Sendero contour, which measures approximately 0.950 inches in diameter at the muzzle before threading. This weight and length distribution, with a 20-inch barrel, makes it balance well for off-hand shooting but adds noticeable mass compared to lighter hunting rifles like the Stevens 334 in .243.
Who is this NOT for?
This rifle is not for the budget-minded shooter looking for a basic, lightweight hunting tool. The 8 lb. weight, proprietary 25 WBY RPM chambering, and focus on modularity come at a cost both in dollars and in the specificity of its mission. If your primary need is a simple, reliable deer rifle that you’ll carry for miles and rarely modify, a more traditional sporter-weight option is a better fit.
What’s in the box?
You receive the rifle with one 5-round AICS-pattern magazine, thread protector, and the standard owner’s manual. The receiver is drilled and tapped for a standard scope base with an 8-40 thread pattern, requiring separate purchase. The adjustable synthetic stock includes spacers for length of pull adjustment, but note the cheek piece adjusts via a hex wrench—you’ll need to provide your own 3/32” Allen key.
Is the Weatherby 307 Range SF worth it at $1089.99?
At $1089.99, it's worth it for the shooter who values modern modularity and plans to use a suppressor. You’re paying for the TriggerTech trigger, the factory Cerakote finish, and the 1:7.5 twist barrel—features that would cost $400-600 to add to a base rifle. If you just want a .25-caliber bolt action and don’t care about threading or aftermarket stocks, you can find options for $200-300 less.

Frequently asked questions
- Does this work with a standard .30 caliber suppressor?
- Yes, but you must use a .30 caliber suppressor with a 5/8-24 direct thread mount. The 25 WBY RPM bore diameter is .257 inches, well under the .30 caliber (.308 inch) bore of most rifle cans. I recommend checking compatibility with your specific suppressor model, like those from SilencerCo or Dead Air, before purchase.
- Is the action compatible with aftermarket chassis systems?
- Yes, the Model 307 action uses a standardized footprint compatible with many chassis from brands like MDT and KRG. The action uses a Remington 700-pattern scope base hole spacing, but always confirm with the chassis manufacturer for your specific model, as inlet dimensions can vary by a few thousandths of an inch.
- How long does shipping take to an FFL?
- Shipping from our warehouse to your chosen FFL dealer typically takes 3-5 business days for in-stock items. After shipment, allow 1-2 additional days for your FFL to log it into their bound book before you can complete the 4473 transfer. The entire process from order to pickup averages 7-10 business days.
- Can I return it if the barrel threading is damaged?
- Returns are accepted within 30 days for defects in manufacture, such as incorrect thread pitch or out-of-spec barrel condition. The thread protector must be intact and unmounted. For damage from customer use, including cross-threading a muzzle device, the rifle would need to be sent to Weatherby’s service center, which has a current turnaround time of 6-8 weeks for barrel work.
