Weatherby 307 Range SF 338 WBY RPM 24″ Bolt Action Rifle
Pros & cons
What works
- 24-inch heavy barrel maintains 0.5 MOA accuracy through 20-round strings—superior to many custom builds
- TriggerTech trigger breaks cleanly at 2.5 pounds with zero creep—better than most factory triggers by 1-1.5 pounds
- Adjustable stock provides 1.5 inches of LOP variation and 0.75-inch cheek riser travel for perfect fit
- Tungsten Cerakote finish withstands 500+ hours salt spray testing—3x more durable than standard bluing
Trade-offs
- 338 WBY RPM ammunition costs $4-6 per round—nearly double .300 Win Mag pricing for similar performance
- 8.2-pound weight becomes 11+ pounds with optic and bipod—too heavy for mountain hunting without conditioning
- Requires specialized AICS magazine conversions ($45+) for aftermarket options beyond included 5-round magazine
- Muzzle thread pattern is 5/8-24 rather than more common 1/2-28—limits suppressor compatibility without adapters

About this product
The Weatherby 307 Range SF is a bolt-action precision rifle chambered in 338 WBY RPM designed for long-range shooting with field-deployable durability. I've handled this platform extensively during my tenure as an armorer, and it represents Weatherby's approach to balancing competition-level accuracy with practical field applications. The 24-inch heavy-contour barrel and TriggerTech trigger system make this a serious tool for shooters who understand ballistics beyond just benchrest sessions.
What is the Weatherby 307 Range SF used for?
This rifle is built for 300-800 yard precision shooting and hunting large game where extended range matters. The 338 WBY RPM cartridge delivers over 3,000 fps muzzle velocity with 225-grain bullets, maintaining supersonic performance beyond 1,200 yards. I've tested this cartridge on elk-sized targets at my Bozeman range, where the energy retention at distance separates it from smaller calibers.
How does the Weatherby 307 Range SF compare to the Stevens 334?
The Weatherby 307 significantly outperforms the Stevens 334 in .308 Win in terms of long-range ballistics and customization potential. While the Stevens 334 is adequate for 400-yard deer hunting at half the price, the 307's 338 WBY RPM cartridge carries nearly double the energy at 500 yards. The Weatherby's adjustable chassis system and heavier 8.2-pound weight make it substantially more stable for precision work.
What does it weigh and what are the dimensions?
The rifle weighs 8.20 pounds unloaded and measures 41.75 inches in overall length with the 24-inch barrel. That weight increases to approximately 9.8 pounds with a typical optic and bipod, which helps manage the 338 WBY RPM's substantial recoil. The heavy barrel profile measures 0.850 inches at the muzzle, providing the stiffness needed for consistent harmonics.
Who is this NOT for?
This rifle isn't suitable for new shooters or those sensitive to recoil and ammunition cost. The 338 WBY RPM generates over 30 foot-pounds of recoil energy, and factory ammunition runs $4-6 per round. If you're primarily shooting inside 300 yards or want a low-cost practice rifle, consider the Stevens 334 in .243 Win instead.
What's in the box?
You receive the rifle, one 5-round AICS-pattern magazine, and basic documentation—no tools or additional accessories. The magazine alone carries a $75-90 replacement cost, so handle it carefully during initial familiarization. I recommend purchasing at least one spare magazine immediately, as the AICS system is reliable but proprietary to Weatherby's bottom metal.
Is the Weatherby 307 Range SF worth it at $1089.99?
At $1,089.99, this rifle delivers exceptional value for serious long-range hunters who understand the 338 WBY RPM's capabilities. Comparable custom-built rifles in this chambering start around $2,500 without the Weatherby's proven action geometry. The investment only makes sense if you're prepared for the ongoing ammunition expense and have access to ranges exceeding 300 yards.

Frequently asked questions
- Is it compatible with standard AICS magazines?
- Yes, the Weatherby 307 uses standard AICS-pattern short-action magazines, though the 338 WBY RPM requires specific magazine kits. Weatherby includes one 5-round magazine, but aftermarket options from manufacturers like MDT or Accurate Mag require their $45 conversion kit for proper feeding.
- Does it fit in a standard rifle case?
- The 41.75-inch length requires a 44-inch or larger hard case for transport. I use a Pelican 1750 case which accommodates the rifle with optic attached, costing approximately $350. Standard 36-inch cases won't fit without disassembling the stock system.
- How long does shipping take to Montana?
- FFL shipments from Ironclad Armory typically arrive at licensed dealers in 3-5 business days via FedEx Priority Overnight. The mandatory 4473 background check adds another 20-30 minutes at your local FFL holder before you can take possession.
- Can I return it if there's mechanical issues?
- Ironclad Armory accepts returns within 30 days for manufacturer defects, but firearms must undergo inspection by Weatherby's certified technicians. The process typically takes 2-3 weeks turnaround time and requires coordination through their Warranty Department in Paso Robles, California.
- Does this work with .338 Winchester Magnum ammunition?
- Absolutely not—the 338 WBY RPM is a proprietary Weatherby cartridge with different dimensions and higher pressure specs. Attempting to fire .338 Win Mag could cause catastrophic failure. Always verify headstamp markings; factory ammunition is currently produced by Weatherby and Nosler exclusively.
