Clymer's Pull Through Chamber Reamers are specially designed for cutting minimum length chambers, providing an accuracy advantage for match rifles.
These reamers require the gun's own bolt for pressure application and are used as a finish reamer after initial chamber cutting with a conventional finish reamer.
The .308 & .30-06 Reamer Sets include a Pull Through Reamer, Thrust Bushing, and a 24" Extension Shaft, compatible with both bolt action and semi-auto rifles.
