The Carlson's Choke Tubes Bismuth Bone Buster is a specialized 20-gauge choke tube engineered for hunters using bismuth shot. Built from 17-4 stainless steel, this mid-range choke delivers the durability and corrosion resistance serious waterfowlers and upland hunters need when reaching out past the close-cover distances. If you're running bismuth ammunition through a Benelli or Beretta shotgun with MobilChoke threads, this tube is purpose-built to handle the harder, denser pellet material without compromise.
Bismuth shot demands different choke geometry than lead or steel—it patterns differently and hits harder at distance. Carlson's engineered this mid-range constriction to optimize bismuth performance while keeping your barrels protected. The 17-4 stainless construction handles the rigors of repeated loading, unloading, and the demanding environments where bismuth shooters operate. Whether you're hunting over water or working dense upland cover, a quality choke tube matched to your ammunition is a small investment that pays dividends in pattern consistency and gun longevity.
Compatibility is straightforward: this tube fits Benelli and Beretta shotguns equipped with MobilChoke threads, making it a direct drop-in for most modern guns from those manufacturers. The mid-range constriction balances pattern density with versatility across typical hunting distances, giving you a single tube that handles the bulk of real-world hunting situations where bismuth excels.

What does mid-range constriction mean?
Mid-range constriction provides a balance between pattern density and shot spread, making it versatile across typical hunting distances where you're likely to encounter birds or game.
Why is 17-4 stainless steel important?
17-4 stainless resists corrosion and wear far better than standard steel, protecting both the choke tube and your barrel threads over years of use, especially in wet or harsh conditions.
