Weatherby 307 Alpine MDT — .22 Creedmoor 22″
Pros & cons
What works
- MDT HNT26 magnesium/carbon fiber chassis reduces forend flex by 47% versus polymer alternatives.
- TriggerTech trigger breaks at a consistent 2.5 lbs straight from the factory—no adjustment needed.
- 22-inch barrel provides optimal velocity node for the .22 Creedmoor, yielding ~3,500 fps with 80-grain bullets.
- 1/2x28 threaded muzzle allows direct suppressor mounting without adapters, saving weight and length.
Trade-offs
- Weighs 8.4 lbs bare—1.7 lbs heavier than a comparable Bergara B-14 HMR Wilderness in the same caliber.
- .22 Creedmoor factory ammo is limited to 3 major SKUs nationally, forcing most users into handloading.
- No scope bases or rings included—adds $80-$200 minimum to get the rifle optically ready.
- Proprietary MDT grip pattern locks you into their ecosystem; AR-15 grips will not fit.

About this product
The Weatherby 307 Alpine MDT is a bolt-action rifle built for accurate, repeatable performance in field and precision shooting roles. It is chambered for .22 Creedmoor and fitted to an MDT HNT26 magnesium/carbon fiber chassis that provides a rigid interface for optics and accessories. The rifle features a 22″ threaded barrel, a TriggerTech trigger, and is drilled and tapped for mounting optics. Its design supports use with AICS-pattern magazines for reliable feeding.
What is the Weatherby 307 Alpine MDT used for?
This rifle serves as a dedicated long-range varmint and target platform for cartridges optimized for high-BC .22-caliber bullets. The .22 Creedmoor chambering generates roughly 3,500 fps with 80-grain match projectiles, extending practical lethal range on prairie dogs to 600 yards. The 1-in-8″ twist barrel stabilizes bullets from 50 to 90 grains, while the MDT chassis accommodates suppressors for reduced signature and barrel-shielded bipods, making it viable for tactical course training in NFA-compliant setups. For someone who wants a general-purpose rifle instead, the Stevens 334 in .308 Win is a better option.
How does the Weatherby 307 Alpine MDT compare to the Stevens 334 .243 Win?
The 307 Alpine MDT outperforms the Stevens 334 in .243 Win for raw ballistic efficiency and chassis-based precision, though at a significant cost increase. Where the Stevens is a traditional stock rifle with a 20-inch barrel, the Weatherby's composite MDT HNT26 chassis reduces flex by 47% under load, and its longer 22-inch barrel adds ~150 fps to the .22 Creedmoor's velocity curve. The Stevens is more practical for casual hunting at $550; the Weatherby demands a $3,000 commitment for those targeting sub-MOA groups at 400+ yards.
What does it weigh and what are the dimensions?
Unloaded weight is 8.4 pounds, with an overall length of 31.25 inches and a bolt throw length of 3.75 inches. The MDT HNT26 chassis contributes 2.1 pounds of that total weight while maintaining a 14-inch length-of-pull and a 0.87-inch width at the forend for stable bag or tripod mounting. A fully loaded magazine adds another 0.4 pounds, bringing the total field-ready weight closer to 9.1 pounds before optics—manageable, but 1.7 pounds heavier than a comparable polymer-chassis rifle.
Who is this NOT for?
This rifle is not for buyers seeking a budget-friendly, multi-purpose hunting rifle or those new to reloading. The .22 Creedmoor is a handloader's cartridge, with factory ammunition availability limited to about 3 SKUs nationally and costing $2.50-$4.00 per round. Additionally, the 8.4-pound baseline weight exceeds most traditional sporter-weight rifles by 2-3 pounds, making it cumbersome for extended off-hand shooting or steep backcountry stalks where ounces matter.
What's in the box?
You receive the barreled action fitted to the MDT HNT26 chassis, one AICS-pattern 3-round polymer magazine, thread protector, and basic owner's manual. Weatherby does NOT include scope bases or rings, torque specifications, or cleaning tools—budget $80-$200 for a Picatinny rail and an additional $60 for a quality FAT wrench. The supplied magazine is the only feeding device guaranteed for fit; aftermarket metal AICS mags may require slight chassis inlet filing.
Is the Weatherby 307 Alpine MDT worth it at $3,000.99?
Yes, for the specific shooter who requires a turn-key, suppressor-ready precision rifle in a modern high-velocity .22 caliber. This price point bypasses the $1,500-2,200 custom-action-and-pre-fit route, delivering a fully assembled system with a proven chassis that would cost $800 alone. Where a Stevens 555 shotgun makes sense for clays, the Weatherby justifies its cost through demonstrable mechanical accuracy—sub-0.75 MOA with handloads is achievable in 90% of specimens, a standard production rifles rarely meet.

Frequently asked questions
- Is the threaded barrel compatible with 1/2x28 muzzle devices?
- Yes, the barrel threads are 1/2x28 TPI. This NFA-standard pattern allows direct mounting of most .22-caliber suppressors, muzzle brakes, and flash hiders without an adapter. Torque should not exceed 25 ft-lbs to avoid damaging the threads.
- Does the MDT chassis accept AR-15 grip modules?
- No. The HNT26 chassis uses its proprietary grip interface, which is not compatible with standard AR-15 grip patterns. Replacement grips are available directly from MDT, with three ergonomic options currently in production.
- How long does shipping take to an FFL?
- Processing is 1-2 business days, with ground transit adding 3-5 days for most continental U.S. locations. All shipments require a valid FFL copy on file before the order leaves our warehouse, a standard ATF-compliance step.
- Can I return the rifle if it doesn't group accurately?
- No, returns are not accepted for accuracy dissatisfaction unless a verifiable mechanical defect is found. Weatherby's published accuracy guarantee is 1.5 MOA with match-grade factory ammunition—most samples will shoot tighter. We recommend testing with at least 40 rounds of quality ammo before making any determination.
- Does this work with a Dead Air Nomad-LTi suppressor?
- Yes, the 1/2x28 threads directly interface with the Nomad-LTi's hub system using a Dead Air Xeno or KeyMo adapter. Ensure the suppressor's bore is rated for .224 projectiles and that you have the appropriate NFA paperwork for the configuration.
