The Carlson's Choke Tubes Bismuth Bone Buster Rem Choke is a 12 gauge extended range choke tube built for hunters who trust bismuth shot in their waterfowl and upland loads. Machined from 17-4 stainless steel, this tube is engineered to handle the harder, denser shot patterns that bismuth ammunition delivers downrange. If you're running bismuth through a Remington-threaded shotgun and want a choke optimized for that payload, this is the precision tool that bridges ammo and barrel.
Bismuth shot patterns tighter and carries further than lead, but it demands a choke that complements that ballistic behavior—not fights it. Carlson's Bone Buster geometry is tuned to that reality, so your patterns stay dense where it counts. Whether you're working a marsh at 40 yards or a field at the edge of effective range, a purpose-built choke makes the difference between a clean harvest and a miss.
The 17-4 stainless construction means durability in wet conditions and resistance to corrosion from repeated bismuth shooting. This is a choke tube that'll outlast the barrels it threads into, and it's designed to be a long-term investment in consistent, repeatable performance.
| Gauge | 12 | |
| Thread Pattern | Remington (Rem Choke) | |
| Material | 17-4 Stainless Steel | |
| Type | Bismuth Bone Buster Extended Range | |
| Model Number | 09209 |
Yes—this choke uses the Remington (Rem Choke) thread pattern, so it fits Remington shotguns and any other gun threaded for that standard.
This choke is optimized for bismuth shot, but the tube itself will function with other shot types. For best results and pattern consistency, match it to bismuth loads.
Bismuth shot is denser and patterns differently than lead. A choke designed for bismuth ballistics delivers tighter, more consistent patterns at extended range, maximizing the advantage of harder shot.
