↬ The Winchester SX4 is a popular shotgun for hunting both ducks and geese, and with the right choke tube, it can deliver consistent patterns with non-toxic shot. The SX4’s versatility allows it to function in even the most challenging environments, but it needs the right choke tube to function effectively.
The Patternmaster Code Black and Carlson’s Cremator are two of the best choke tubes for the Winchester SX4. They can deliver results of over 80% pellets inside a 30-inch circle at over 40 yards with the right ammo. Their ported design helps reduce recoil and muzzle jump, making follow up shots quicker and more accurate.
In this guide, we’ll discuss in more detail why you should consider these chokes, the features behind them, and what to expect at certain hunting distances. And remember, always pattern your shotgun to see how it performs with the ammo you plan on hunting with so adjustments can be made prior to using it in the field.

Top Chokes for the Winchester SX4
These are the three chokes you should consider for the Winchester SX4 that can produce more consistent results for ducks and geese. The SX4 is compatible with the Invector Plus choke system.
1) Carlson’s Cremator Choke Tube
Carlson’s choke tubes fit Winchester SX4 shotguns and their Cremator lineup of chokes happens to work extremely well for ducks and geese. This mid-range choke patterns similar to a modified choke size, perfect for medium range shots over decoys. The Cremator is capable of putting over 80% of pellets in a 30-inch circle at 40 yards consistently with the right ammo.
The Cremator uses a unique design that consists of multiple tapers, which work together to gradually compress the shot column, helping to provide a more consistent shot pattern. This makes the Cremator ideal for hunting situations where you need to be able to adjust your shooting style quickly and accurately. This is the TOP pick.

2) Patternmaster Code Black Choke Tube
The Patternmaster Code Black is a top-of-the-line choke tube that provides unmatched performance for long-range hunting situations. This choke tube uses a specialized constriction design that helps to control the spread of shot at longer distances. This makes it an ideal choice for waterfowl hunters who need to take shots at moving targets from a distance.
Patternmaster uses internal studs that halt the wad so that it doesn’t interfere with shot column separation. This results in a controlled separation that translates to better patterns. It fits Winchester SX4 shotguns and is a great all-around choke tube for ducks, geese, turkey, and dove out to 50 yards. Expect it to perform closer to a full choke. This is the pick for MAX range.

3) Carlson’s TSS Choke Tube
TSS is a dense new tungsten pellet available for turkey hunting and it happens to pattern really tight with Winchester SX4 shotguns. This TSS choke by Carlson’s fits the SX4 and can deliver 90% or more of TSS pellets in a 10-inch circle at 40 yards. TSS pellets have a density of 18 g/cc which is almost pure tungsten. For comparison, the density of lead is only 11 g/cc.
If you are thinking about switching to TSS since it’s the new ammo on the market, this TSS choke is a good starting point to fine tune loads that work at the ranges you’ll be hunting.

- Extended choke tubes perform better at longer ranges and can help reduce the need for a choke wrench

- Axial ports drilled into the choke can help reduce barrel jump and also reduce recoil

Types of Chokes for the Winchester SX4 Shotgun
Ported vs. Non-ported chokes – Ported chokes have groves and holes that allow for pressure expansion and wad stripping technology to help create better patterns. Non-ported chokes are smoothed walled and can even be flush with the end of the barrel.
Extended vs. flush chokes – All ported chokes are extended chokes. Extended chokes usually extend 1 to 1.5 inches past the end of the barrel. This added barrel length can help improve patterns by increasing the parallel section of the choke tube and allowing space for wad technology to work.
The best chokes for hunting are always extended ported chokes like the Carlson’s Cremator. Extended chokes are ideal for waterfowl and turkey hunting because they provide a platform for tighter constrictions and wad technology improvements beyond that of flush factory chokes.
To harvest waterfowl and old toms at long ranges consistently, an extended ported choke is the best starting point to developing a tight pattern that will produce great results at 50 yards or more.

When it comes to choosing the right choke tube for the Winchester SX4, Carlson’s Cremator stands out from its competitors.

Unlike its competitors, the Cremator is built with Triple Shot Technology, which ensures that the shot is evenly distributed, reducing the chances of having holes or gaps in your pattern. Additionally, the Cremator’s ports and longer parallel section helps to reduce recoil, which in turn leads to more controlled shots and better follow ups. Overall, the Carlson’s Cremator is a top performer, delivering outstanding results that set it apart from the competition.
