Bismuth has quietly become the go-to non-tox load for hunters who want more thump than steel without the sticker shock of tungsten, and Carlson's built the Bone Buster specifically to make those loads perform. This is the 09214, a Mid-Range choke for 20 gauge shotguns running Beretta Mobilchoke, Benelli Standard, or Franchi Standard threads. It carries a .025 constriction and a .595 inch diameter, machined from 17-4 heat-treated stainless steel with a non-reflective matte black finish that won't flash and spook birds on the water.
The secret is inside the tube. Carlson's cut a longer parallel section than you'll find in most factory or aftermarket chokes, which gives the shot column more time to settle down before it leaves the muzzle. The result is tighter, more even patterns that hold together downrange. Carlson's did a pile of load testing to dial this in, and the payoff shows up on the pattern board where it counts.
Despite the name, this choke isn't a one-trick pony. The Mid-Range constriction runs beautifully with bismuth, but it also handles lead, Hevi-Shot, and all steel shot, so you can leave it in the barrel across a mixed bag of hunts. Where it really shines is that 20 to 45 yard window, which covers most decoying ducks, timber shooting, and close-in goose work. Slugs, sabots, and rifled slugs should stay out of it.
Every Bone Buster is made in the USA and backed by Carlson's lifetime warranty, so if anything ever goes wrong with the tube you send it back for a replacement. For a 20 gauge waterfowler looking to squeeze real performance out of bismuth without switching to expensive tungsten, this is a smart, no-nonsense upgrade.
This choke is threaded for the Beretta Mobilchoke system as well as Benelli Standard and Franchi Standard 20 gauge shotguns. Double check your barrel's choke system before ordering, since Carlson's makes the Bone Buster in separate fits for Remington, Winchester, Benelli Crio, and Beretta Optima HP guns.
You're not limited to bismuth at all. This Mid-Range tube is rated for all steel shot along with lead and Hevi-Shot loads, so it makes a versatile everyday waterfowl choke. Just keep slugs, sabots, and rifled slugs out of it.
The .025 Mid-Range constriction is dialed in for roughly 20 to 45 yards. That covers most decoying ducks, timber hunts, and closer goose setups. If you're consistently reaching out past 45 yards, the Extended Range version of the Bone Buster would be the better call.
Bismuth is denser than steel and behaves differently in the barrel, so it responds well to tuning. The Bone Buster's longer parallel section settles the shot column for tighter, more even patterns than a typical factory choke. Carlson's did extensive load testing to get this right, and it shows up on the pattern board.
