Description
A .410 is a fun little gun, but it takes the right choke to turn one into a legitimate turkey killer. That's exactly what Carlson's built here. This TSS Turkey Choke Tube is dialed in for Tungsten Super Shot and the smaller turkey loads, sizes 7 through 9, so you get a dense, even pattern that carries plenty of energy well past where most folks expect a .410 to reach.
The constriction measures .385 with a turkey-tight profile, and the whole point is putting the most pellets possible inside a 10-inch circle at 40 yards. TSS is heavy stuff, running about 22 percent denser than heavyweight shot and roughly 56 percent denser than lead, which is what lets a small gauge hit way above its weight class. Pair this choke with Federal Premium Heavyweight TSS loads and you've got a setup that keeps toms in trouble out to distances that used to be off the table for a .410.
What Makes This Carlson's .410 Choke Tick
It's machined from 17-4 stainless steel and wears a matte black finish, so it holds up to the punishment TSS dishes out while shrugging off weather and wear in the turkey woods. This is the Short Invector (1.5-inch flush) version, which fits the Stevens 301, Mossberg International SA-410, and other .410 guns cut for the Win-Choke and Browning standard Invector systems. It's a flush-mount tube, so it sits clean at the muzzle without an extended collar sticking out.
Getting the Most From Your TSS Turkey Choke
Do yourself a favor and pattern your gun before opening day. Every barrel throws a slightly different pattern, so a few rounds at a target sheet will tell you exactly where your dense core lands and how far you can stretch it. One thing worth noting: this choke is built for TSS and lead, not big steel. Keep steel shot to #4 or smaller, and skip slugs and sabots entirely.

Frequently Asked Questions
What shotguns does the Carlson's .410 TSS Turkey Choke fit?
This is the Short Invector (1.5-inch flush) version, so it fits .410 guns threaded for the Win-Choke and Browning standard Invector systems. That includes popular options like the Stevens 301 and Mossberg International SA-410. If you're unsure which system your barrel uses, check your owner's manual or the markings on your existing choke before ordering.
Can I run steel shot through this TSS turkey choke tube?
It's designed and optimized for Tungsten Super Shot and lead turkey loads in sizes 7 through 9. You can use steel, but only in #4 or smaller, and you should avoid slugs, sabots, and rifled slugs entirely. TSS is where this choke really shines, so that's what you'll want feeding it for the best patterns.
What kind of range can I expect from a .410 with this choke?
This choke is built to put the maximum number of pellets inside a 10-inch circle at 40 yards, which is the standard turkey pattern test. Paired with quality TSS loads, plenty of hunters are comfortably taking toms out to 40 yards and beyond with a .410. Your exact effective range depends on your gun and load, so pattern it before you head out.
Why does TSS make such a difference in a small gauge like the .410?
Tungsten Super Shot is dramatically denser than lead, about 56 percent denser, which means each pellet carries more downrange energy and you can drop to smaller shot sizes without losing punch. That lets a .410 hold a dense, lethal pattern at distances that used to belong to the 12 gauge. This choke is tuned to make the most of that density.
