The Carlson's Choke Tubes 09217 Bismuth Bone Buster is a specialized extended-range choke tube engineered for 20-gauge shooters using bismuth ammunition in Benelli Crio and Crio Plus shotguns. If you're hunting waterfowl or upland game with non-toxic shot and want better pattern density at distance, this stainless steel tube is built to handle the demands of bismuth loads without the wear that softer materials experience.
Constructed from 17-4 stainless steel, the Bone Buster delivers the durability needed for bismuth's harder, denser pellets. Bismuth ammunition kicks back harder and runs hotter than lead, so tube material matters—this one won't degrade or copper-fowl your bore over repeated use. The extended-range constriction is optimized to tighten patterns at distance, keeping shot centered on target where it counts.
Benelli Crio and Crio Plus owners will appreciate a choke specifically matched to their platform's threading and specifications. Whether you're working open water or brush, the Bone Buster pairs with bismuth loads to give you the pattern control needed for ethical, confident shots. Installation is straightforward—remove, screw in, verify secure seating.

Frequently Asked Questions
Will this choke work in other 20-gauge Benelli models?
This tube is designed for the Crio and Crio Plus. Verify your shotgun model before ordering, as choke threading varies across Benelli's lineup.
Can I use this choke with lead ammunition?
The Bone Buster is engineered for bismuth loads. While it may function with lead, it is optimized for bismuth's harder composition and extended-range shooting.
Why does material matter for bismuth chokes?
Bismuth pellets are significantly harder and denser than lead. Softer steel or aluminum chokes can wear prematurely under the friction and impact. The 17-4 stainless steel in this tube resists that wear and maintains pattern consistency over time.
