Bismuth has become the go-to non-toxic option for folks who want steel-safe performance without the harshness on older or fixed-choke guns, and Carlson's built the Bone Buster line specifically to get the most out of it. This 20-gauge tube runs a .040 constriction, which puts it in the extended range category, so it's tuned for reaching out and keeping pellets grouped tight when the birds are hanging out at the far edge of your comfort zone.
The Bone Buster is CNC-machined from 17-4 heat-treated stainless steel, and it uses a longer parallel section inside the tube than you'll find on most factory chokes. That extended parallel section is the real trick here, giving the shot column more time to settle before it leaves the muzzle, which translates to denser, more even patterns downrange. Carlson's did a good bit of load testing while developing these, and it shows in how consistently they throw bismuth.
This particular tube (part number 09225) is cut for the Winchester choke system, which also covers most Browning Invector, Mossberg 500, Weatherby, and Savage 20-gauge shotguns. Worth noting: if you've got a Winchester SX2, SX3, SX4, SXP, or newer Supreme, those take the Invector Plus pattern instead, so double-check your barrel before ordering. While it's optimized around bismuth, it plays nicely with lead and Hevi-Shot loads too, and it'll handle steel shot as long as you keep it #2 or smaller.
If you're chasing ducks, geese, or upland birds with bismuth ammo and want your 20 to punch above its weight, this is the kind of choke that earns its keep. It's made in the USA and backed by Carlson's lifetime warranty, so a busted tube just gets mailed back for a replacement. Pattern it with a few different loads at the range and you'll dial in a setup that hits hard well past what a stock choke gives you.
This tube uses the Winchester choke system, which covers most Winchester, Browning Invector, Mossberg 500, Weatherby, and Savage 20-gauge shotguns. If you run a Winchester SX2, SX3, SX4, SXP, or newer Supreme, those use the Invector Plus pattern instead, so verify your barrel before ordering. When in doubt, the fitment is usually stamped on the barrel.
Yes. Even though it's optimized for bismuth, it works with lead and Hevi-Shot loads with no problem. For steel, keep your shot size to #2 or smaller through this extended range tube.
The extended range Bone Buster runs a .040 constriction, which tightens up the shot column more than a mid range or factory choke. Combined with the longer parallel section inside the tube, it keeps pellets grouped denser at longer distances. That means more effective reach when birds are working the far edge of your range.
It is. Carlson's backs their choke tubes with a lifetime warranty, and they're made in the USA. If anything happens to the tube, you package it up and send it back for a replacement.
