Chadwick & Trefethen ''C'' Adjustable Reamer
$76.99
The Chadwick & Trefethen 'C' Adjustable Reamer is a precision gunsmithing tool designed for barrel work on 10 and 12 gauge shotguns. Built for gunsmiths and serious shotgun enthusiasts who need to open or true gauge dimensions with precision, this reamer delivers clean, controlled cuts without chatter—a hallmark of quality gunsmithing work. Whether you're fitting a replacement barrel, correcting bore issues, or finishing a custom shotgun build, the 'C' reamer gives you the control and repeatability that separates professional results from sloppy work.
The blade angle is engineered to eliminate chatter and produce a smooth finish with every cut. This matters: chatter marks weaken the barrel wall and create stress points. A clean reaming pass means a barrel that'll hold up to years of hunting and shooting. The adjustable design lets you dial in exactly the dimension you need, making it a versatile addition to any gunsmithing bench or serious reloader's toolkit.
Note that tightly choked 12 gauge barrels may require the use of a 'D' reamer before using the 10/12 gauge 'E' reamer, depending on your specific barrel and project. If you're working with premium or heavily choked 12 gauge barrels, plan your reaming sequence accordingly.
