Weatherby Model 307 Barreled Action Review with Magpul PRO 700 Chassis

A Modular Precision Rifle Built Your Way

The Weatherby Model 307 barreled action marks a major step forward for Weatherby Rifles, officially entering the custom and builder-style precision rifle market. Designed around the Remington 700 footprint, the Model 307 allows shooters to build a rifle exactly how they want—without sacrificing Weatherby’s renowned quality, reliability, and accuracy guarantees.

In this review, I put two Weatherby Model 307 barreled actions through their paces, pairing them with the Magpul PRO 700 chassis system and testing them on steel targets from 200 metres out to 500 metres. This is a real-world field review focused on performance, modularity, and shootability—not just specs on paper.

What Is the Weatherby Model 307 Barreled Action?

The Weatherby Model 307 is a modern, precision-focused bolt action built to the Remington 700 pattern, making it compatible with a huge range of aftermarket chassis systems, stocks, triggers, and accessories. By releasing the Model 307 as a factory barreled action, Weatherby gives shooters the freedom to create a truly custom rifle—while still backing it with their sub-MOA accuracy guarantee.

Key Features of the Weatherby Model 307 Barreled Action

Remington 700 footprint compatibility
Factory-installed TriggerTech adjustable trigger
Sub-MOA accuracy guarantee
Smooth, precision-machined bolt action
Factory-fit barrels with multiple profile options
Built for hunting, long-range shooting, and precision rifle applications

This approach makes the Model 307 ideal for shooters who want custom rifle performance without the headaches of full gunsmith builds.

The Two Rifle Builds Tested

To properly evaluate the flexibility of the Model 307 platform, I built two very different rifles, each tailored for a specific role.

.308 Winchester – Magpul PRO 700 Light Chassis

The first rifle is a .308 Winchester Weatherby Model 307, featuring a spiral-fluted barrel, radial muzzle brake, and a durable brown Cerakote finish. This barreled action was installed into the Magpul PRO 700 Light chassis (non-folding).

Setup highlights:

Magpul PRO 700 Light chassis
Zerotech Trace Advanced 4–24×50 RMG scope
Magpul MOE M-LOK bipod
AICS-pattern magazines
Full-length M-LOK on forend and sides
QD sling points and traditional rifleman’s loop

This configuration is perfectly suited to long-range target shooting, field work, and precision hunting, offering excellent ergonomics and stability while remaining relatively lightweight for its class.

6.5 Creedmoor – Magpul PRO 700 Folding Chassis

The second build focuses on versatility and low-light capability. This 6.5 Creedmoor Weatherby Model 307 uses the Sendero profile barrel and is installed in the Magpul PRO 700 folding chassis in OD Green.

Setup highlights:

Magpul PRO 700 folding chassis
Adjustable length of pull and cheek riser
Thermion XP60 thermal optic
M-LOK-mounted Arca rail section
Magpul bipod
QD sling cups front and rear

This rifle was built as a night-time and thermal shooting platform, capable of transitioning seamlessly between bipod, tripod, and vehicle-based shooting positions.

Magpul PRO 700 Chassis – Precision and Practicality

The Magpul PRO 700 chassis system is a standout option for Remington 700–pattern actions, and it pairs exceptionally well with the Weatherby Model 307.

Why the Magpul PRO 700 Works So Well

Rigid aluminium backbone for consistency
Tool-less adjustable cheek riser and length of pull
Folding or fixed stock options
Extensive M-LOK compatibility
Excellent ergonomics for prone and positional shooting
AICS magazine compatibility

Whether used for precision rifle competition, long-range hunting, or tactical-style shooting, the PRO 700 provides stability, comfort, and modularity without unnecessary complexity.

Live Fire Testing: Steel from 200m to 500m

Both rifles were tested on steel targets at 200 metres, 300 metres, and 500 metres, using real-world ballistic data rather than idealised range conditions.

Results

Consistent first-round impacts at 200m and 300m
Reliable steel hits at 500 metres after minor elevation refinement
Smooth bolt operation and excellent trigger feel under rapid firing
Predictable recoil impulse, especially with the muzzle brake on the .308

The TriggerTech triggers deserve special mention—they provide a clean, consistent break that enhances precision shooting straight out of the box.

Thermal ballistic calculations on the 6.5 Creedmoor setup proved accurate and repeatable, further highlighting the versatility of the Model 307 platform for both day and night applications.

Who Is the Weatherby Model 307 For?

The Weatherby Model 307 barreled action is ideal for:

Shooters wanting a custom Remington 700–style build without full custom costs
Long-range shooters and precision rifle enthusiasts
Hunters who value modularity and accuracy
Thermal and night shooting setups
Anyone wanting Weatherby quality with build-your-own flexibility

Final Verdict: One of the Best Factory Barreled Actions Available
