Action Truing

ACTION TRUING

WHAT WE DO

The terms action truing and squaring are the same. Some call it blueprinting. It all means the same thing. It is the process of bringing everything in alignment with the bolt bore raceway. The action threads are the single point cut to bring them in alignment with the bolt bore raceway. The locking lug recesses and the receiver face is machined so they will be perfectly perpendicular to the center line of the action.

 The bolt is indicated and machined so all surfaces are perpendicular to the actions mating surfaces. The bolt face is machined so it is concentric and 90 degrees to the bolt raceway. The bolt nose is lightly machined just to true it up as it is just a clearance cut. The recoil lug is surface ground or replaced with a new one. The heart of every accurate rifle starts with an accurately machined action. We recommend replacing your barrel when having your action trued. 

During the truing process the action threads are recut, therefore your old barrel will no longer fit. Without cutting off the old threads, rethreading and chambering of the old barrel will be required. It is money well spent to invest in a new match quality barrel rather than machining the old one. You will be glad that you did. Action truing alone does not guarantee small groups, as it is only one of the many factors that go into building a consistently accurate rifle.
