Description
When spring gobbler season rolls around, the choke in the end of your barrel does a lot of the heavy lifting. Carlson's Extended Turkey Choke in 20 gauge with a .575 constriction is built to pull your shot string together into a tight, even pattern so more pellets land in the kill zone. It carries Carlson's part number 10300 and fits the Winchester / Browning Invector / Mossberg 500 thread pattern, which also covers a lot of Weatherby and Savage pump and semi-auto guns.
The tube is machined from 17-4 heat-treated stainless steel, so it stands up to the heavy buffered turkey loads folks run these days without wearing out. It wears a matte blue finish and sticks out about an inch past the muzzle, giving you that extended profile that makes it easy to grab and swap.
What Makes the 10300 Turkey Choke Pattern So Tight
The real trick is the 1.050 inch parallel section inside the tube. That extra-long straight run settles the shot before it leaves the barrel, which tightens the core of your pattern and cuts down on the random fliers that open things up. It is a noticeable step up from the factory full choke most 20 gauges ship with, and a lot of hunters find they can reach out a little farther with confidence.
Loads That Work With the Carlson's Extended Turkey Choke
This choke is happy with lead, copper-plated lead, Bismuth, and Hevi-Shot turkey loads. If you are running TSS or steel, keep it to shot sizes #4 and smaller. One quick note on fitment: Winchester SX-P, SX-2, SX-3 and SX-4 models actually take Browning Invector Plus tubes, so double-check your gun before ordering. Carlson's makes all of their tubes in the USA and backs them with a lifetime warranty, so you are set for a lot of seasons in the turkey woods.

Frequently Asked Questions
What shotguns does the Carlson's 10300 turkey choke fit?
It uses the Winchester / Browning Invector / Mossberg 500 thread pattern, which also covers many Weatherby and Savage 20 gauge shotguns. Keep in mind that Winchester SX-P, SX-2, SX-3 and SX-4 models use Browning Invector Plus tubes instead, so verify which pattern your barrel is threaded for before ordering.
What constriction is this extended turkey choke?
This is the .575 inch turkey constriction for 20 gauge. That tighter squeeze is designed to pack your pattern together for longer, more dependable shots on gobblers compared to a standard full choke.
Can I shoot TSS or steel through the Carlson's turkey choke?
Yes, with a limit. TSS and steel loads should be #4 shot or smaller through this tube. Lead, copper-plated lead, Bismuth and Hevi-Shot turkey loads are all fair game.
What is the choke made of and will it hold up?
It is CNC machined from 17-4 heat-treated stainless steel, which handles the heavy buffered turkey loads hunters run without trouble. Carlson's makes it in the USA and backs it with a lifetime warranty, so it is built to last many seasons.
