Description
Picture this: you’re in a Missouri river bottom, the light’s fading, and you need a rifle that can reach out and decisively anchor a big whitetail or a hog at 250 yards without the punishing recoil of a magnum. That’s the exact scenario where the Savage MSR10 Hunter in .338 Federal starts to make a whole lot of sense. I’ve put a few boxes of Federal Fusion through this rig, and it fills a specific, powerful niche.
So, what is the Savage MSR10 Hunter Semi-Automatic 338 Federal 16.125″ Barrel, Adjustable Black Stock Black Hard Coat Anodized, 20rd? It’s a gas-operated, semi-automatic hunting rifle built on a hardened, anodized aluminum receiver. It’s designed to deliver the potent .338 Federal cartridge with the fast follow-up shot capability of an AR-10 platform, all in a relatively compact, adjustable package ready for serious game. At $1205.07, it sits in a competitive spot for a purpose-built hunting AR.
Let’s talk about the heart of it: the .338 Federal cartridge. This isn’t your plinking round. It’s essentially a .308 Winchester case necked up to hold a .338″ bullet, creating a short-action powerhouse that drives heavy, high-sectional-density projectiles with authority. Think of it as a modern .35 Remington with better ballistics. Out of this rifle’s 16.125-inch barrel, you’re looking at excellent terminal performance on medium to large game without the muzzle blast and recoil of a .338 Win Mag. The adjustable gas block is a key feature here—it lets you tune the system to run smoothly with a suppressor, which I highly recommend for this setup.
The build quality feels solid. The black hard coat anodized finish on the upper and lower is durable for field use. One of the best features is the adjustable Magpul MOE SL stock—it’s a simple, robust design that lets you get the length of pull just right, whether you’re wearing a t-shirt or a heavy winter coat. The rifle comes with a 20-round Magpul PMAG, which is generous, but for actual hunting, I’d probably load it with 5 or 10. The whole package weighs in at a manageable around 8.5 pounds unloaded, so it’s not a featherweight sporter, but it balances well.
Here’s the thing—a huge advantage is that it’s built to standard AR-10 pattern specs. This means a vast world of aftermarket parts is open to you. The handguard uses a common mounting system, the trigger is a standard mil-spec unit (an easy upgrade point), and the buffer system is familiar. The rifle is drop-in ready for optics, and I found it cycled Federal and Hornady factory ammo without a hiccup right from the start.

Pros: The .338 Federal is a legit hunting cartridge with great stopping power. The semi-auto platform allows for quick shots. The adjustable stock and gas system add versatility. It’s built on a common, customizable AR-10 pattern. The price is fair for a complete, capable rifle.
Cons: .338 Federal ammo isn’t as common or cheap as .308. It’s heavier than a bolt-action in the same caliber. The mil-spec trigger is serviceable but begs for an upgrade for precision work.
Who is this for? This is for the hunter who wants more than a .308 but doesn’t need a long-range magnum. It’s perfect for dense woods, driving hogs, or hunting in bear country where a fast second shot matters. It’s also for the shooter who appreciates the modularity of the AR platform but wants it dedicated to a hunting role. This rifle ships to Missouri and compliant US states through your local FFL.
Frequently Asked Questions
Q: How does .338 Federal compare to .308 Winchester?
A: The .338 Fed uses the same case but fires heavier, wider bullets (typically 180-210 grain vs. 150-180 for .308). This translates to more energy transfer and better penetration on game, with slightly less range. Recoil is a bit sharper, but very manageable in this gas-operated rifle.
Q: Is the barrel threaded for a muzzle device?
A: Yes, the barrel comes threaded 5/8″-24, which is the standard for .30 caliber cartridges. This allows you to easily add a muzzle brake, compensator, or (most usefully) a suppressor to tame sound and recoil.
Q: Can I use my existing AR-10 magazines?
A: It depends. The Savage MSR10 Hunter is designed to work with SR-25/DPMS pattern magazines. The included Magpul PMAG 20 LR/SR Gen 3 is the standard, and most magazines built to that pattern should function. Always test compatibility with a few rounds first.
If you’re looking for a capable, modern hunting rifle that breaks from the traditional bolt-action mold and offers serious power in a compact package, the Savage MSR10 Hunter in .338 Federal deserves a close look. Check availability for transfer to your local dealer.
