Description
The Browning BAR MK3, .300 Winchester Short Mag, 23″, 3rd, Turkish Walnut is a gas-operated, semi-automatic hunting rifle built for power and fast follow-up shots. It chambered in the flat-shooting .300 WSM cartridge, features a 23-inch barrel for optimal velocity, and is dressed in a classic Turkish Walnut stock. It’s a modern, reliable workhorse for serious big-game hunters.
I’ve put a few boxes of .300 WSM through this platform, and here’s what stands out. The gas-operated action soaks up a significant amount of the stout recoil you’d expect from this magnum cartridge—it’s noticeably more shootable than a bolt gun in the same caliber. The fit and finish are pure Browning, with deep, rich bluing and that hand-rubbed Turkish Walnut stock that just feels right in the field. It’s a rifle that balances classic aesthetics with modern semi-auto functionality.

Look, the .300 WSM is no joke—it’s a magnum cartridge designed to compete with the .300 Win Mag in a shorter, more efficient package. This 23-inch barrel is the sweet spot for harnessing its potential without becoming unwieldy in a blind or thick timber. At a price of $1302.17, you’re getting Browning’s renowned reliability in a package that’s ready for the most demanding North American game. The rifle is drop-in ready for optics, requiring no gunsmithing to mount a quality scope from brands like Leupold or Vortex using standard bases.
Who This Rifle Is For
This BAR MK3 is for the hunter who appreciates the speed and reduced perceived recoil of a semi-auto but doesn’t want to sacrifice the power and range needed for elk out west or moose up north. It’s for the shooter who values a classic wood-and-steel presentation but demands modern performance. If you’re covering big country where a second or third shot might be the only one you get, this system makes sense. It’s also a great choice for hunters in Missouri pursuing longer-range opportunities or those who travel out of state for larger game.
Pros & Cons
Pros: The gas system genuinely tames the .300 WSM’s recoil, making practice and follow-up shots more practical. The build quality is excellent, and the Turkish Walnut stock is a cut above typical factory wood. The detachable magazine is a huge convenience in the field. Browning’s reputation for durability in semi-auto hunting rifles is well-earned.
Cons: .300 WSM ammo can be more expensive and less ubiquitous than some standard calibers. The rifle is not lightweight, so if you’re counting every ounce on a mountain hunt, that’s a consideration. As with any semi-auto, it’s mechanically more complex than a bolt-action.
Frequently Asked Questions
Q: Is the .300 WSM suitable for whitetail deer in Missouri?
A: Absolutely, but it’s serious overkill for most typical shots. It’s a fantastic cartridge for larger game like elk, moose, or bear, and it shines at longer ranges. For dedicated whitetail hunting in timber, a lighter-recoiling caliber is often a more pleasant choice.
Q: What type of scope base does it use?
A: The BAR MK3 uses a standard dovetail-style scope mount system. It’s compatible with Browning BAR-specific bases from major manufacturers like Leupold (Part # 53565) or Warne. Installation is straightforward.
Q: How does the semi-auto action handle in cold weather?
A: The gas system is robust and designed to cycle reliably in various conditions. As with any firearm, proper maintenance is key. Keeping it clean and lightly lubricated with a quality oil suited for cold temperatures will ensure reliable function during late-season hunts.
This Browning BAR MK3 in .300 WSM is a purpose-built tool for the serious big-game hunter. It combines proven power with the practical advantage of a semi-automatic action. This model is available at firearms-missouri.com for Missouri residents and nationwide. If you’re ready to step up to a magnum-caliber semi-auto that doesn’t compromise on quality or performance, this is a rifle worth a long, hard look.
