Blue Printing Services

The 100% Bowers blueprint incorporates an entire reworking of a rifle’s action and bolt, turning a sloppy factory action into a quality, super–accurate bench rest quality action. Every rifle under going the blueprinting process is personally hand crafted by Steve using skills developed as a time served tool maker with the care and attention to detail rarified in most modern engineering practices.

The Process

We hand–lap the bolt race using diamond lapping paste to ensure a perfectly concentric and parallel race.
The action is mounted on a mandrel and ground between centres to true up it’s O/D and tenon shoulder (this ensures complete parallelism and roundness to the action), and also ensures that the front face is exactly 90° to the bore axis.
The action is mounted in a precision collet and the tenon threads re–machined and lead threds removed for a spigot location diameter, bolt lugs trued to the action centre–line.
The front face is drilled and reamed to fit the custom recoil lug and pin.
The bolt is ground between centres, then sleeved or nickel/hard chrome plated and reground to give 0.001” fit in the body. Lugs, shroud and bolt face are reground to give an exact 90° lock–up in the body.
The action can be finished either by plating, blueing or specialist paint finishing.
