Description
When you're leaning on TSS ammo to reach a tom holding tight, the choke matters just as much as the shell. Carlson's built this extended tube around a .555 constriction that squeezes those tiny, dense tungsten pellets into a tight cluster, putting the most shot possible inside a 10-inch circle at 40 yards. It's cut for the Winchester Choke / Browning Invector thread pattern and fits most Winchester, Browning Invector, Mossberg 500, Weatherby, and Savage 20 gauge shotguns.
What Sets This Carlson's TSS Turkey Choke Apart
This tube is machined from 17-4 heat-treated stainless steel with a non-reflective matte black finish, so it stands up to the heavy, buffered pressure of hard-hitting turkey shells without flinching. Tungsten Super Shot is about 22 percent denser than Heavyweight shot and roughly 56 percent denser than lead, which means smaller pellets carry more downrange energy and let you run higher pellet counts in loads like #7 and #9. The choke is tuned to make the most of that density.
Running the .555 Turkey Choke in the Field
The extended, knurled body sticks out about an inch past the muzzle and gives you enough grip to hand-tighten or back it out without hunting for a wrench. While it's optimized for Federal Premium Heavyweight TSS loads, it patterns well with other quality turkey ammunition in the smaller 7 to 9 shot range too. Serious turkey hunters have reported clean, dense patterns capable of headshots out past 50 yards, which is exactly what you want when a bird hangs up just outside comfortable range.
One thing worth noting: this is a turkey-specific choke meant for lead, tungsten, and Hevi-type payloads. Keep steel shot larger than #4 out of it, and you'll get a lifetime of dependable service from it.

Frequently Asked Questions
What shotguns does this Carlson's TSS turkey choke fit?
It's cut for the Winchester Choke / Browning Invector thread pattern and fits most Winchester, Browning Invector, Mossberg 500, Weatherby, and Savage 20 gauge shotguns. If you run a Winchester SX2, SX3, SX4, SXP, or 101, those use the Invector Plus pattern instead, so you'd want the matching Invector Plus version. When in doubt, check the choke system stamped on your barrel or listed in your owner's manual.
Can I shoot regular lead or Hevi-Shot loads through this choke, or only TSS?
You're not locked into TSS. The tube is optimized for Federal Premium Heavyweight TSS loads but patterns well with lead, tungsten, and Hevi-type turkey ammo in the smaller 7 to 9 shot sizes. The one rule to follow is no steel shot larger than #4 through a turkey choke this tight.
What kind of range can I expect from the .555 TSS turkey choke?
The .555 constriction is built to put the maximum number of pellets inside a 10-inch circle at 40 yards. Paired with quality TSS ammo, hunters have reported dense patterns capable of clean headshots out past 50 yards. As always, pattern your specific gun and load combo at the range before you count on those distances.
Is this choke made to hold up to heavy turkey loads?
Yes. It's machined from 17-4 heat-treated stainless steel specifically to handle the pressure of heavy, buffered turkey shotshells. The matte black finish is non-reflective so it won't flash and spook a wary tom, and the stainless build resists corrosion in wet spring conditions.
