Description
The Winchester SX4 Waterfowl Hunter 12 Gauge 28-inch is a gas-operated autoloader built for the hard work of marsh and wetland hunting. Its Active Valve gas system cycles everything from light 2-3/4 inch target loads to heavy 3-inch magnums without a hiccup. The Woodland camo dip breaks up your outline against cattails and timber, and the back-bored barrel with Invector-Plus chokes delivers tight, even patterns on passing ducks. This is a working gun, plain and simple.

Key Features
- Active Valve Gas System — Why it matters: It self-regulates gas pressure to cycle light target loads and heavy 3-inch steel shot reliably without manual adjustment. You won’t short-stroke on a limit of teal.
- Back-bored Barrel with Chrome Chamber — Why it matters: The overbore reduces recoil and shot deformation, while the chrome lining resists corrosion from steel shot and damp marsh conditions. Keeps your bore clean and your patterns tight.
- Hydro-dipped Woodland Camouflage — Why it matters: This isn’t a paint job; it’s a bonded film that won’t peel or flake in saltwater or mud. It breaks up your silhouette against flooded timber, cattails, and open water.
- Invector-Plus Choke Tubes — Why it matters: These extended-length tubes produce denser patterns than standard flush chokes. You get three constrictions (Full, Modified, Improved Cylinder) to match your range and target.
- Inflex Recoil Pad — Why it matters: The proprietary gel pad soaks up felt recoil from heavy 3-inch loads, letting you stay on target for fast follow-up shots on a crossing drake.
Who It’s For
This shotgun is for the duck and goose hunter who spends more time in waders than in a blind. It’s for the shooter who wants a reliable autoloader that doesn’t need constant tinkering. If you hunt public marshes, timber holes, or coastal estuaries, the SX4 Waterfowl Hunter is built for that environment.
Pros & Cons
- Pro: Cycles reliably with light 1-ounce target loads and 3-inch magnums straight out of the box.
- Pro: The Woodland camo is durable and effective in most Southern wetland settings.
- Con: The fixed synthetic stock does not allow for shim adjustments to change drop or cast. Shooters with a strong cross-dominance may need a gunsmith for an aftermarket stock.
- Pro: Chrome-lined chamber and bore resist rust and pitting from steel shot and humid air.
- Con: The trigger pull is a bit heavy at around 7 pounds (per Winchester specs) — not ideal for fast wing shooting, but workable.

Frequently Asked Questions
Does the Winchester SX4 Waterfowl Hunter cycle light target loads?
Yes. The Active Valve gas system self-regulates to cycle everything from 1-ounce target loads to 3-inch magnums. You may need to break it in with a few boxes of heavy loads first, but it reliably runs light loads after that.
What choke tubes come with the gun?
It ships with three Invector-Plus flush mount tubes: Full, Modified, and Improved Cylinder. These are steel shot rated. You can also use any standard Invector-Plus tube from Winchester or Browning.
Is the camo finish durable in saltwater?
Yes. The hydro-dipped Woodland camouflage is bonded to the synthetic stock and matte metal finish. It resists salt spray, mud, and UV fading better than paint or tape. Just rinse it with fresh water after a salt marsh hunt.
Can I shoot 3-1/2 inch shells in the SX4 Waterfowl Hunter?
No. This model has a 3-inch chamber. It is designed for 2-3/4 inch and 3 inch shells only. For 3-1/2 inch capability, look at the SX4 Longbeard or a dedicated 3-1/2 inch gun.
What is the barrel length and is it back-bored?
The barrel is 28 inches and is back-bored (oversized bore) to reduce felt recoil and improve pattern density. The chamber and bore are chrome plated for corrosion resistance against steel shot.
