Carlson's Choke Tubes 09225 Bismuth Bone Buster WinChoke, Browning Invector, Mossberg 500 20 Gauge Extended Range 17-4 Stainless Steel

The Carlson's Choke Tubes 09225 Bismuth Bone Buster is a 20-gauge extended-range choke built for hunters who demand precision and durability when shooting bismuth loads. Machined from 17-4 stainless steel, this tube is engineered to handle the harder, denser bismuth pellets used in non-toxic waterfowl and upland hunting—a material that demands a more robust choke than lead shot. If you're running a Winchester WinChoke, Browning Invector, or Mossberg 500 in 20 gauge, this extended-range design patterns bismuth loads tight and consistent, giving you the reach you need to ethically take birds at distance.

Stainless steel construction means this choke resists corrosion and wear from the abuse of field hunting, whether you're in wet, salty, or heavily hunted terrain. Extended-range chokes are tighter constrictions designed to keep shot patterns dense farther downrange, crucial if you're relying on bismuth's ballistic properties to reach targets beyond typical 20-gauge range. This is purpose-built gear for the serious 20-gauge hunter who won't compromise on material choice or performance.

Carlson's reputation in the choke tube business is built on quality manufacturing and thoughtful design. This tube fits seamlessly into your existing Winchester, Browning, or Mossberg platform—no gunsmithing required. Drop it in, head to the field, and trust that your shot will go where it needs to go.

Frequently Asked Questions

Will this choke fit my 20-gauge shotgun?

The Carlson's 09225 fits Winchester WinChoke, Browning Invector, and Mossberg 500 shotguns in 20 gauge. Verify your shotgun's choke system before ordering to ensure compatibility.

Can I use this choke with lead shot?

This choke is specifically designed and optimized for bismuth shot, which is harder and denser than lead. While the stainless construction is robust, the extended-range constriction is tuned for bismuth ballistics. Check with Carlson's or your manufacturer for lead-shot recommendations if you plan to alternate loads.

What does extended-range mean on a choke tube?

Extended-range chokes have a tighter constriction than standard or improved cylinder chokes, keeping your shot pattern denser at longer distances. This is especially valuable with bismuth, which benefits from the tighter pattern to maintain energy and effectiveness downrange.

Is stainless steel necessary for a choke tube?

Stainless steel resists rust and corrosion, particularly valuable in wet hunting conditions or salty environments. It also handles the harder bismuth pellets without accelerated wear, making it a durable choice for frequent hunters and non-toxic ammunition users.
