Rougher vs. Finisher – How 184050130 Fits In
Clymer offers Rimless Rifle Chambering Reamers in both rougher and finisher styles:
Rougher reamers are approximately .010" undersize and do not cut the throat, ideal for high-volume shops that want to preserve their finish reamers. Primary Tactical+2Brownells+2
Finishing reamers like 184050130 bring the chamber to final size and cut the throat to spec.
If you’re only cutting a few 22-250 chambers, this finishing reamer alone is usually sufficient. For production-level work, combine it with a rougher to extend tool life and improve shop efficiency. Primary Tactical+1
