Carlson's Bismuth Bone Buster 20G Choke Tube
Precision 17-4 stainless steel choke tube optimized for bismuth ammunition. Extended range design produces dense, devastating patterns in 20-gauge shotguns with Beretta Optima HP threading.
Bismuth Bone Buster Choke Tube for 20-Gauge Shotguns
The Bismuth Bone Buster choke tube represents a purposeful departure from conventional factory designs. Carlson's engineers recognized that bismuth ammunition—with its unique ballistic characteristics—demands a choke tube specifically engineered for its performance envelope.
Design and Construction
Precision Engineering: CNC-machined from 17-4 heat-treated stainless steel, this choke tube is built to exacting tolerances and designed to last a lifetime of shooting.
Extended Parallel Section: The longer parallel section inside the choke creates a more gradual constriction pattern compared to standard factory tubes. This design principle, refined through extensive field testing, optimizes shot column compression for bismuth loads.
Performance Characteristics
- Bismuth Optimization: Tested extensively with various bismuth loads to deliver the dense, bone-crushing patterns bismuth ammunition is known for
- Versatile Ammunition Compatibility: Works effectively with bismuth, lead, and Hevi-Shot loads
- Extended Range Capability: Rated for all steel shot not larger than #2, extending your shooting options
Specifications
- Gauge: 20-gauge
- Fit: Beretta Optima HP threading
- Material: 17-4 stainless steel
- Finish: Corrosion-resistant
This is a tool for serious upland hunters and clay shooters who demand pattern density and reliability from their equipment.
