Precision 17-4 stainless steel choke tube optimized for bismuth ammunition. Extended range design delivers dense, devastating patterns with bismuth, lead, and Hevi-Shot loads.
The Bismuth Bone Buster choke tube represents a thoughtful engineering solution for shooters who rely on bismuth ammunition. Carlson's designed this tube specifically to produce the dense, consistent patterns that bismuth loads demand.
17-4 Heat Treated Stainless Steel — CNC precision machined for durability and reliability. The extended parallel section inside the choke creates superior shot column control compared to conventional factory tubes.
Extensive testing with various bismuth loads ensures you'll get the devastating, bone-crushing patterns this choke delivers. The extended range design works equally well with:
If you're serious about bismuth shooting, this choke tube gives you the precision tool to maximize your ammunition's potential. Dense patterns mean more birds in the bag and fewer wounded birds in the field.
