Features 

Weatherby guarantees sub-MOA accuracy with this rifle. The trigger is a TriggerTech unit. Pull is clean with a predictable break. Bolt disassembly is tool-less, which makes field cleaning quicker than on most competing actions. The Accubrake is included and does a meaningful job of cutting felt recoil on a rifle this light in .270 Win. The barrel is fluted sporter profile. 
 

Use Cases 

The .270 Win chambering and 24" barrel work well for deer and elk at distance. The walnut stock and Cerakote finish hold up in field conditions, though the walnut isn't as moisture-resistant as synthetic alternatives. At 7.5 lbs it's manageable for a day afield without getting oppressive at the bench.

The 307 Adventure SD in .270 Win draws consistent praise for its walnut stock. Most owners appreciate the traditional look and feel in a modern action. Accuracy is the other recurring positive: users frequently report sub-MOA groups, which aligns with Weatherby's guarantee, and the rifle holds up well at longer ranges.

The TriggerTech trigger gets favorable comments for its clean pull. Bolt operation is generally described as smooth. The .270 Win chambering is seen as a practical choice, enough power for larger game with recoil that's manageable, especially with the Accubrake installed.

On the critical side, price comes up regularly. Some buyers feel the premium over comparable bolt guns is steep, though most who go hands-on with it tend to decide the fit and finish justify it. Weatherby customer service gets mixed marks. Some users report prompt, helpful support, others describe difficulty getting issues resolved. A handful of discussions compare it unfavorably to competing rifles at the same price with better aftermarket parts availability.
