Reciprocating Action Universal Receiver Test System

Abstract

A firearm reciprocating and locking bolt and associated barrel, utilized in and with a locking firearm action, that places fixed ammunition and its associated chamber down-bore effectively past the constraints of the receiver.

What is claimed is: 
     
         1 . A reciprocating and locking bolt action firearm bolt, having a total length and geometry whereby the face of the bolt, when prior art bolt lugs are locked to any prior art bolt action receiver, extends substantially equal to or past the most forward location of a prior art bolt action firearm receiver, being made of metal alloy, incorporating a prior art firing pin, prior art bolt handle, prior art firing pin spring, prior art bolt diameters, prior art bolt lug location, and functions to lock the receiver-bolt interface and fire a cartridge as a prior art firearm receiver action and prior art bolt is intended, to chamber pressures in excess of 65,000 pounds per square inch. 
     
     
         2 . A recessed chamber, whereby when located in a threaded gun barrel, and that barrel fully screwed into a prior art threaded receiver action, and that receiver action fit with the claimed bolt, places it substantially equal to or past the most forward location of an attached threaded firearm receiver, and permits the location of a prior art pressure measurement device past the most forward location of a prior art receiver.
