Description
Picture this: you’re tucked against a Missouri oak, the first hint of dawn just starting to bleed through the timber. You hear that distant gobble, and you need a shotgun that’s as light and fast as your heartbeat, but hits with the authority to anchor a tom at 40 yards. That’s the exact scenario the Winchester SX3 NWTF Cantilever Turkey 20 Ga, 24″ Barrel, 3″ Chamber, Mossy Oak Break Up Infinity Finish was built for. I’ve put a few boxes of heavy 20-gauge TSS through one, and it’s a purpose-driven machine that makes a compelling case for leaving the 12-gauge in the safe.
So, what is it? The Winchester SX3 NWTF Cantilever Turkey is a gas-operated semi-auto shotgun chambered in 20-gauge with a 3″ chamber. It features a 24″ barrel with a cantilever scope mount integrated into the receiver, all dressed in Mossy Oak Break-Up Infinity camo. It’s designed for the mobile turkey hunter who wants a lightweight, maneuverable package with optics-ready versatility.
Why This 20-Gauge is a Turkey Slayer
Look, the big story here is the move to 20-gauge without sacrificing terminal performance. Modern tungsten super shot (TSS) loads have completely changed the game, giving the 20-gauge patterns and penetration that rival older 12-gauge setups. This gun capitalizes on that. The 24″ barrel is the sweet spot—long enough for a clean burn and tight pattern, but short enough to swing through brush without hanging up. At just over 6.5 pounds, it feels like a feather compared to a fully dressed 12-gauge, which is a godsend when you’re covering ground or holding still for a long sit.
The cantilever mount is the other half of the genius. It’s machined as part of the receiver, not the barrel. This means you can mount a red dot or low-power scope directly to the gun’s frame, and it stays zeroed even if you remove the barrel for cleaning or transport. No gunsmithing required. It’s a rock-solid platform for optics like a Vortex Venom or a Burris Fastfire, which are perfect for the precise shot placement turkey hunting demands. The gun ships with a set of fiber-optic rifle-style sights, but let’s be honest, you’re mounting an optic on this rig.

The Good & The Considerations
Pros: The weight—or lack thereof—is the first thing you’ll notice. It’s incredibly fast-handling. The gas-operated SX3 action is famously soft-shooting, which is nice when you’re testing patterns with heavy turkey loads. The cantilever mount system is brilliantly simple and utterly reliable. And the Mossy Oak Break-Up Infinity finish is effective; it just disappears in the spring woods.
Cons: At a price point of $1000.53, it’s an investment. You’re paying for a specialized tool. The stock is a fixed length of pull, which fits most shooters well, but won’t accommodate everyone perfectly without modification. And while the 20-gauge with TSS is devastating, if you’re a hunter who refuses to move away from traditional lead 12-gauge loads, this might not be your hammer.
Who This Shotgun Is For
This is for the dedicated turkey hunter. Specifically, it’s for the hunter who covers miles of Ozark hills, who sets up and tears down multiple times a morning, and who values a quick, accurate shot over raw payload. It’s also an excellent choice for younger or smaller-framed hunters who need a manageable gun that still gets the job done decisively. If your style is more “run-and-gun” than “sit-and-wait,” this shotgun is your partner.
Frequently Asked Questions
Q: Is the scope mount really that secure?
A: Yes. Because it’s part of the receiver, not the barrel, it provides a stable, non-moving platform. Your zero stays true. It’s a far superior system to mounts that attach to the barrel itself.
Q: What’s the real-world range with a 20-gauge turkey setup?
A: With today’s high-density TSS ammunition and the right choke—like the included extended turkey tube—this setup is consistently lethal out to 40 yards and often beyond. Pattern your specific load to know your exact ethical limit.
Q: Does it cycle lighter target loads reliably?
A: The SX3’s Active Valve gas system is self-regulating. I’ve found it cycles everything from 7/8 oz. target loads up to the heaviest 3″ magnum turkey loads without adjustment. It’s a versatile action.
