Description
The 7mm Backcountry was built to push heavy bullets fast out of short barrels, and Weatherby leaned into that idea with the 307 Range SF. The 20 inch heavy contour barrel keeps the whole rifle at 39.5 inches overall, which makes a real difference threading through timber or sliding it into a scabbard, and the cartridge still delivers velocities you'd normally need a 24 inch tube to reach. The barrel is threaded 5/8×24 and wears an Accubrake up front, which takes a serious bite out of felt recoil so you can stay on the glass and watch your hits.
Built on the Model 307 Action
The 307 is Weatherby's most open platform, a two-lug, fully cylindrical action that plays nice with a huge range of aftermarket stocks, triggers, rails, and mounts. The bolt strips down without tools for easy cleaning in camp and runs an M16 style extractor for positive extraction and ejection. Feeding comes from a Magpul detachable magazine, and the rifle accepts AICS pattern mags if you want more capacity or spares you already own. The drilled and tapped steel receiver is ready for whatever optic setup you prefer, and every 307 is built at Weatherby's Sheridan, Wyoming facility with a Sub-MOA accuracy guarantee behind it.
Range SF Fit and Feel
The synthetic stock has an adjustable cheekpiece and adjustable length of pull, so you can dial in proper eye alignment behind a big scope instead of craning your neck. Textured touch points keep your grip planted in wet weather, and dual front swivel studs let you run a bipod and sling at the same time. The externally adjustable TriggerTech Field trigger breaks with zero creep and adjusts down to 2.5 pounds, and the Cerakote finish on the barrel, receiver, and stock shrugs off moisture and hard miles. At 7.9 pounds bare, it carries fine for a heavy barrel rig and settles in nicely for longer shots, whether that's a steel plate or an elk across a basin.

Frequently Asked Questions
What is 7mm Backcountry and why pair it with a 20 inch barrel?
7mm Backcountry is Federal's high-pressure cartridge built around a strong alloy case, and its whole purpose is producing magnum-level velocity from shorter barrels. That makes the 20 inch Range SF a natural match, giving you a compact, easy-carrying rifle that still has the legs for long range work on elk, mule deer, and steel.
Does the Weatherby 307 Range SF take aftermarket magazines and accessories?
Yes, and that's one of the best parts of the Model 307 platform. It ships with a Magpul detachable magazine and accepts AICS pattern mags, and the action is compatible with a wide range of aftermarket 700 pattern stocks, triggers, rails, and mounts. The receiver comes drilled and tapped, so mounting an optic is straightforward.
Is the 307 Range SF covered by an accuracy guarantee?
It is. Every Model 307 rifle carries Weatherby's Sub-MOA guarantee, meaning a 3-shot group of .99 inches or less at 100 yards from a cold barrel with Weatherby factory or premium ammo, within two years of verified purchase. The heavy barrel and TriggerTech Field trigger make that kind of accuracy very repeatable.
How adjustable is the trigger and stock on this rifle?
The TriggerTech Field trigger is externally adjustable down to 2.5 pounds with a zero-creep break and very short overtravel. The synthetic stock has an adjustable cheekpiece and adjustable length of pull, so you can set up proper eye alignment behind your scope and get a fit that matches your build and shooting position.
