Claims
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.

INVENTOR
[0006] No disclosure of this invention was made at any time before
the provisional patent filing date of May 20, 2016.
BACKGROUND OF THE INVENTION
(1) Field of the Invention
[0007] Pressure Testing of Smallarm Ammunition
(2) Description of Related Art
[0008] A falling block Universal Receiver is capable of accepting
pistol, rifle, shotshell or rim fire pressure-test barrels. This
same Universal Receiver Action provides for direct access of
electronic and non-electronic pressure measurement devices mounted
directly over and/or into the specific cartridge/chamber region of
the test barrel. However, the falling block designed Universal
Receiver is expensive. The manufacture of such falling block
Universal Receiver is highly involved. The weight of such falling
block Universal Receiver is cumbersome. Parts are not readily
available.
[0009] A common reciprocating-action receiver can be utilized to
pressure-test "rifle" ammunition, because the chamber of a rifle
cartridge can extend out past the forward receiver ring of a
reciprocating-action receiver. Therefore, an electronic or
non-electronic pressure measurement device can be placed directly
over and/or into the specific cartridge/chamber region of the test
barrel, without also drilling, threading or otherwise compromising
the reciprocating-action receiver. Likewise, any number of
chambered test barrels can individually be screwed or otherwise
attached to a reciprocating-action receiver, so long as the
relationship of chamber and bolt face maintain correct "head
space". Thus, a single reciprocating action receiver could function
as a universal receiver for "rifle cartridges".
[0010] However, the forward location of the bolt face incorporated
in a standard reciprocating-action centerfire rifle firearm
receiver is within the housing of the receiver ring. This bolt face
location prevents this same firearm receiver action from providing
direct access to pistol, rim-fire and shot shell chambers, at the
location of their respective "pressure chamber". This standard bolt
face location precludes reciprocating-action receivers from being
used as "Universal Receivers" for all smallarm ammunition.
[0011] Firearm receivers such as break-action and Baumann-type
(U.S. Pat. No. 3,996,684) forward-biased bolt face receivers are
incapable of withstanding the high pressures generated in 65000-psi
intended centerfire rifle cartridges.
BRIEF SUMMARY OF THE INVENTION
[0012] A reciprocating and locking bolt body for a firearm
receiver. The invention is a modified bolt, and associated modified
gun barrel(s), whereby the location of the locking interface
between the bolt body and action receiver remain unchanged, but the
bolt face is extended even with or past the opening face of the
action receiver ring. This modified bolt face location allows
pistol, rim-fire or shot shell chambers to be placed forward of the
firearm receiver/barrel junction, and thus provide for direct
access of electronic and non-electronic pressure measurement
devices mounted directly over and/or into the barrel of any
cartridge/chamber region under test. The firearm receiver remains
entirely intact and unaltered from prior art design and intent. The
firearm receiver remains entirely capable of withstanding chamber
pressures in excess of 65,000-psi.

DETAILED DESCRIPTION OF THE INVENTION
[0024] The claimed bolt incorporated into a prior art firearm
action receiver has an extended face-to-lug relationship, such that
the face of the bolt that touches/pushes the cartridge into the
chamber, when in forward and locked position, extends to or beyond
the end of the firearm action receiver ring. The effective length
of the claimed bolt body enables a prior art and economical
long-action firing pin to be utilized within the bore of the
claimed bolt body.
[0025] Of necessity, any such barrel joined with a prior-art
receiver, and utilizing this elongated face-to-lug relationship
claimed bolt, must be cut with a recessed chamber. The individual
modified bolt, as well as the required and modified location of the
recessed chamber are both claimed within the constraints of the
invention.
[0026] Together, the elongated bolt and recessed chamber are
utilized to fire a cartridge beyond the constraints of the firearm
receiver. In achieving this relationship, one individual,
economical, lightweight, common-place firearm action receiver is
now capable of interfacing with any number of ammunition test
barrels, and any number of calibers, whereby electronic or
non-electronic measurement devices can be placed beyond the action
receiver, and those measurement devices placed directly over or
into the specific chamber, measuring direct chamber pressure,
without altering the material strengths nor function of the firearm
receiver. The preferred embodiment permits a bolt-action receiver
forward threaded ring to remain entirely intact and unaltered from
prior art design and intent.
