Create Super-Accurate Minimum Headspace Chambers
The Clymer .30-06 Pull Through Chamber Reamer Set (184300306) is engineered specifically to produce minimum-length, tight-headspace chambers in .30-06 Springfield rifles. That means:
Enhanced accuracy potential in match and precision hunting rifles
More consistent ignition and brass support
Reduced chance of case stretching and premature brass failure
By tightening up headspace to the lower end of spec, this pull-through system helps give your rifle the same kind of accuracy advantage match shooters have relied on for decades. Brownells UK+1
How the Pull-Through System Works
Unlike a standard chamber reamer used from the breech, this Clymer tool is designed to work as a pull-through reamer from the muzzle end: Brownells UK+2Brownells Finland+2
The reamer is attached to the 24" extension shaft and guided into the bore from the muzzle.
The rifle’s own bolt applies pressure to the reamer from the rear.
As you turn the shaft from the muzzle end, the reamer gradually cuts the chamber.
When the bolt finally “drops” and closes freely, the chamber has reached the desired minimum headspace.
This method uses the rifle’s bolt as a live gauge, ensuring the chamber is cut exactly to the rifle’s headspace relationship, not just theoretical dimensions.
Finish Reamer Only – For Final, Precision Cuts
Clymer specifies that these Pull Through Chamber Reamers are to be used as FINISH REAMERS ONLY: Brownells UK+2Brownells Finland+2
First, rough and finish the chamber with a conventional finish reamer to standard dimension.
Then, use the .30-06 Pull Through Reamer to carefully bring the chamber down to minimum headspace.
This two-step approach:
Minimizes wear on your P/T reamer
Gives finer control over final headspace
Ensures a smooth, SAAMI-spec final surface in the shoulder, neck, and throat
Improved Design – Cuts Shoulder, Neck & Throat
This updated design from Clymer doesn’t just “kiss” the shoulder; it is engineered to cut the shoulder, neck, and throat in one continuous, controlled operation. Brownells UK+2Brownells Finland+2
Benefits include:
More uniform neck and throat geometry
Reduced risk of neck crimping or excessive bullet constriction
Better bullet alignment into the rifling for improved accuracy
For match shooters and custom rifle builders, that means more consistent chamber-to-bore transition and more predictable performance shot to shot.
