Finisher-Only – When Precision Matters More Than Volume
Within the .22 Rimfire Rifle/Auto Pistol/Revolver Reamer line, Clymer offers both roughers and finishers for some applications. Roughers are .010" undersized and omit the throat, saving wear on the finisher when many chambers are being cut. Brownells+2Red River Reloading+2
However, if you’re:
Cutting only a few chambers, or
Performing final-size work on an existing chamber,
a finish reamer like the F22LRC is all you need. It brings the chamber to final dimensions and cuts the throat, giving you a ready-to-use .22 LR chamber when used with proper technique and lubrication. Red River Reloading+2Brownells UK+2
Solid Pilot & Integral Throat for True, Concentric Chambers
To maintain alignment and accuracy, Clymer designs their rimfire reamers with: Brownells UK+3Primary Tactical+3Brownells Österreich+3
Six right-hand cutting, straight flutes – stable cutting, efficient chip removal
Solid pilot – keeps the reamer centered in the bore or cylinder
Integral throat – throat geometry is ground into the reamer for a smooth bullet transition into the rifling
This geometry minimizes chatter, promotes a mirror-like surface finish, and helps ensure that each chamber ends up straight, concentric, and consistent—critical for accuracy and long brass life.
