Description
Serious turkey hunters know the difference between a choke that just fits and one that turns a decent gun into a long-range tack driver. Carlson's built this TSS Turkey tube around modern tungsten loads, dialing in a tight .555 constriction that keeps the maximum number of pellets inside a 10-inch circle at 40 yards. The extended profile reaches about an inch past the muzzle, which helps the shot column settle for cleaner, more even patterns when the bird is hanging up out past comfortable range.
What Makes This 20 Gauge TSS Choke Tick
The tube is machined from 17-4 heat-treated stainless steel, so it stands up to the heavy buffered pressures that today's tungsten turkey shells generate. Finished in a non-reflective matte black that won't flash and spook a wary tom, it carries a knurled end that lets you thread it in and back it out by hand without digging for a wrench. Carlson's designed it specifically for the Beretta and Benelli Mobil choke system, so if your 20 gauge runs Mobil threads, this drops right in.
Getting the Most From the Carlson's TSS Turkey Tube
This choke is tuned for Federal Premium Heavyweight TSS loads, but it pairs beautifully with any quality turkey ammo running smaller shot in the #7 to #9 range. Tungsten Super Shot is denser than lead, which means more pellets and more downrange energy, and this constriction was built to take full advantage of that. It handles lead, copper-plated, bismuth, and Hevi-Shot too, giving you room to experiment at the patterning board.
One thing worth remembering: this is a tungsten and lead tube, not a steel shot choke, so keep the steel loads out of it. Spend an afternoon patterning a few different shells and you'll find the sweet spot that puts a nasty cluster right where the bead sits.

Frequently Asked Questions
Will this Carlson's TSS Turkey choke fit my 20 gauge shotgun?
This tube is cut for the Beretta and Benelli Mobil choke system, so it fits 20 gauge shotguns running Mobil threads. If you're unsure, check the top of your barrel or your gun's manual for the choke system it uses. Matching the thread pattern is what keeps everything running safe and true.
What shot can I run through the TSS Turkey choke tube?
It's optimized for Federal Premium Heavyweight TSS loads and works great with other turkey ammo in the #7 to #9 range. It also handles lead, copper-plated, bismuth, and Hevi-Shot. Just keep steel shot out of it, since this tube isn't built for that.
Why choose the .555 constriction for turkey hunting?
The tight .555 constriction is designed to keep the most pellets possible inside a 10-inch circle at 40 yards. That density is exactly what you want for reliable headshots on a gobbler at longer distances. Pattern a few loads through it and you'll dial in the sweet spot for your setup.
Is this an extended choke and does it come with a wrench?
Yes, this is an extended tube that reaches roughly an inch past the muzzle, which helps produce cleaner, more consistent patterns. It ships with a standard choke wrench, and the knurled end also lets you thread it in and out by hand in the field.
