The Carlson’s Choke Tubes Bismuth Bone Buster Invector-Plus 12 Gauge Mid-Range 17-4 Stainless Steel Made a Bold First Impression
I’ve spent over a decade immersed in the world of outdoor and tactical gear, and I’ve seen countless products come and go. However, the Carlson’s Choke Tubes Bismuth Bone Buster Invector-Plus 12 Gauge Mid-Range 17-4 Stainless Steel immediately piqued my interest with its promise of enhanced performance specifically tailored for bismuth ammunition in the field. This choke tube seemed designed to optimize patterns and deliver devastating results.
My search for a choke tube that could reliably handle bismuth shot for waterfowl hunting initially led me to this particular Carlson’s offering. Steel shot alternatives are increasingly necessary in certain hunting areas, and bismuth stands out as a non-toxic option with ballistics that closely mirror lead. The Carlson’s Bismuth Bone Buster seemed like the ideal solution to maintain effective hunting ranges while adhering to environmental regulations.
The packaging was straightforward, but the choke tube itself felt substantial the moment I held it. The 17-4 stainless steel construction instilled immediate confidence in its durability and resistance to the harsh elements often encountered during waterfowl hunts. The finish was clean, and the threads appeared precisely cut, promising a secure fit within my shotgun barrel.
I was considering a similar choke from Briley and another from Patternmaster, both reputable names in the industry. However, the Carlson’s model offered a compelling combination of a specialized design for bismuth, a mid-range designation (addressing my typical hunting distances), and a price point that felt like a sweet spot. My first impression was one of cautious optimism; I was eager to see if it lived up to its claims.
Real-World Testing: Putting Carlson’s Choke Tubes Bismuth Bone Buster Invector-Plus 12 Gauge Mid-Range 17-4 Stainless Steel to the Test
First Use Experience
My initial test of the Carlson’s Choke Tubes Bismuth Bone Buster Invector-Plus 12 Gauge Mid-Range 17-4 Stainless Steel took place at a local shooting range. I wanted to gauge the pattern consistency and density at various distances before taking it into the field. The weather was slightly overcast with a light breeze, conditions that provided a realistic simulation of typical hunting scenarios.
The choke tube was incredibly easy to install, threading smoothly into my Benelli Super Black Eagle II’s Invector-Plus barrel. After a few test shots with standard lead target loads to confirm proper installation and alignment, I switched to a variety of bismuth loads from different manufacturers (Kent Cartridge, Browning, and Hevi-Shot). The patterns at 30 and 40 yards were noticeably tighter and more consistent than with the factory modified choke I usually use. There were no noticeable issues with recoil or unusual sound signatures.
There were no unexpected surprises during the initial range session; the Bone Buster performed exactly as advertised. The ease of installation and the immediate improvement in pattern density were definitely encouraging.

It has been exposed to rain, mud, and freezing temperatures without any signs of rust or corrosion. The 17-4 stainless steel construction has indeed held up remarkably well.
Cleaning and maintenance have been straightforward; a simple bore brush and solvent are all that’s needed to remove any residue. I’ve noticed no loosening or degradation of the threads, indicating a robust and precise manufacturing process. Compared to previous aftermarket chokes I’ve used, the Carlson’s model offers a noticeable improvement in pattern consistency with bismuth loads, resulting in cleaner kills and fewer wounded birds.
This choke has exceeded my initial expectations. Its durability, ease of use, and, most importantly, its ability to consistently deliver dense and effective patterns with bismuth shot make it an invaluable addition to my waterfowl hunting setup.
