Description
This is the tube you reach for when you're loading up tungsten and want your 20 gauge to hit way above its weight class. Carlson's built the TSS Turkey choke around Federal Premium Heavyweight TSS loads, and it thrives on the smaller 7 through 9 shot sizes that TSS ammo is famous for. Because TSS pellets carry roughly 56 percent more density than lead, a good matching constriction like this .555 keeps them stacked tight and moving with energy well past where old lead loads run out of steam.
What Makes the TSS Turkey Choke Tick
The body is machined from 17-4 heat-treated stainless steel and finished in a non-reflective matte black, so it shrugs off the buffered, high-pressure turkey shells you're going to run through it. The extended, knurled end is the part you'll appreciate in the field. It threads in and backs out by hand, no wrench digging around in your vest at zero-dark-thirty. It uses the Rem Choke thread pattern, so it drops right into Remington-threaded 20 gauge barrels and the many guns that share that system.
Patterning With the Carlson's TSS Turkey Tube
The whole point of a tight turkey choke is putting the maximum number of pellets in a 10-inch circle where a gobbler's head and neck live. Folks running #7 and #9 TSS through this tube consistently report dense, even patterns holding together out to 40 yards and beyond, with plenty of guns stretching further. A word to the wise: this thing patterns so tight up close that at short range you want to be deliberate about your aim. Like any choke, pattern your specific gun and load combo before opening day so you know exactly where it's throwing lead and how far you can stretch it.
One thing to keep in mind is what NOT to feed it. This is a turkey choke through lead, copper-plated, bismuth, Hevi-Shot and TSS. Keep steel shot larger than #4, slugs, sabots and buckshot out of it. Carlson's backs the tube with a lifetime warranty and builds them in the USA.

Frequently Asked Questions
Will this TSS Turkey choke fit my 20 gauge shotgun?
It's built on the Rem Choke thread pattern, so it fits Remington-threaded 20 gauge barrels along with the wide range of guns that use that same system. Before ordering, check that your barrel is marked for Rem Choke or verify it in your owner's manual. If you're unsure what threads your gun uses, we're glad to help you match it up.
What ammo works best in the Carlson's TSS Turkey Choke Tube?
It's tuned for Federal Premium Heavyweight TSS loads and performs great with other turkey ammo in smaller 7 through 9 shot sizes. You can also run lead, copper-plated, bismuth and Hevi-Shot through it. Just keep steel shot larger than #4, slugs, sabots and buckshot out of any turkey choke.
How does the .555 constriction affect patterns?
The tighter .555 constriction squeezes those dense TSS pellets into a compact swarm, which is exactly what you want for headshots on turkeys at distance. Hunters regularly report even, tight patterns holding out to 40 yards and past. Every gun is a little different, so pattern your setup before the season to nail down your effective range.
Do I need a tool to install this choke?
Not necessarily. The extended, knurled end lets you thread it in and out by hand, which is handy out in the field. A standard choke wrench is included in the box if you want to snug it down tight or need extra grip.
