Abstract

The present invention includes a device for determining the force necessary for the separation of a bullet from an ammunition cartridge comprising a chamber housing having central bore extending from a lower housing end to an upper housing end and terminating at a upper aperture, wherein the central bore comprises a chamber diameter adapted to accept an ammunition cartridge and that the bullet partially extends from the upper aperture; a frustaconical shape shoulder in the central bore at the upper housing end to reduce the chamber diameter to mate to an ammunition cartridge shoulder; a neck that connects the upper aperture to the frustaconical shape shoulder adapted to accept an ammunition cartridge neck; a cartridge retention lip within the upper aperture adapted to contact an ammunition cartridge bullet aperture; a chamber mount adapted to connect the chamber housing and a testing device; a bullet securing device comprising a bullet securing end to secure the bullet and a bullet securing device mount adapted to connect to the testing device; a moving mechanism to move the bullet securing device away from the chamber housing; a sensor in communication with the moving mechanism to measure a force exerted by the moving mechanism; and a display in communication with the sensor to display and or record the force.

First claim

What is claimed is:

1. A device for determining the force necessary for the separation of a bullet from an ammunition cartridge comprising:
a chamber housing having a central bore extending from a lower housing end to an upper housing end and terminating at a upper aperture through the upper housing end, wherein the central bore comprises a chamber diameter adapted to accept an ammunition cartridge and that the bullet partially extends from the upper aperture; a frustaconical shape shoulder in the central bore at the upper housing end to reduce the chamber diameter to mate to an ammunition cartridge shoulder; a neck that connects the upper aperture to the frustaconical shape shoulder adapted to accept an ammunition cartridge neck; a cartridge retention lip within the upper aperture adapted to contact an ammunition cartridge bullet aperture;
a chamber mount adapted to connect the chamber housing to a testing device surface;
a bullet securing device comprising a bullet securing end to secure the bullet and a bullet securing device mount adapted to connect to the testing device;
a moving mechanism to move the bullet securing device away from the chamber housing;
a sensor in communication with the moving mechanism to measure a force exerted by the moving mechanism; and
a display in communication with the sensor to display and or record the force.

2. The device of claim 1 , wherein the chamber mount attaches to a platform.

3. The device of claim 1 , wherein the chamber mount comprises a housing adaptor that connects the chamber mount to a platform.

4. The device of claim 1 , wherein the bullet securing device comprises a collet, a clamp, a vice, chuck, or any other mechanism.

5. The device of claim 1 , wherein the central bore accepts a caliber selected from 17, 22, .22-250, .223, .243, .25-06, .270, .300, .30-30, .30-40, 30.06, .300, .303, .308, .338, .357, .38, .380, .40, .44, .45, .45-70, .50 BMG, 5.45 mm, 5.56 mm, 6.5 mm, 6.8 mm, 7 mm, 7.62 mm, 8 mm, 9 mm, 10 mm, 12.7 mm, 14.5 mm, 20 mm, 25 mm, 30 mm, 40 mm and others.

6. A method of determining the force necessary for the separation of a bullet from an ammunition cartridge comprising the steps of:
providing a chamber housing comprising a central bore extending from a lower housing end to an upper housing end and terminating at a upper aperture through the upper housing end, wherein the central bore comprises a chamber diameter adapted to accept an ammunition cartridge and that the bullet partially extends from the upper aperture; a frustaconical shape shoulder in the central bore at the upper housing end to reduce the chamber diameter to mate to an ammunition cartridge shoulder; a neck that connects the upper aperture to the frustaconical shape shoulder adapted to accept an ammunition cartridge neck; a cartridge retention lip within the upper aperture adapted to contact an ammunition cartridge bullet aperture;
inserting the ammunition cartridge into the central bore to extend the bullet through the upper aperture;
securing the chamber housing to a platform;
connecting a bullet securing device to the bullet such that the bull is connected to the bullet securing device;
wherein the bullet securing device is in communication with a moving mechanism to move the bullet securing device away from the chamber housing;
a sensor in communication with the bullet securing device to measure one or more properties of the movement of the bullet securing device relative to the chamber housing;
moving the bullet securing device away from the chamber housing;
separating the bullet from the ammunition cartridge; and
recording the one or more properties that correlates to the separation of the bullet from the cartridge.

7. The method of claim 3 , further comprising the step of displaying the one or more properties to a display.

8. The method of claim 3 , further comprising the step of comparing the one or more properties to a standard or reference.

9. The method of claim 3 , wherein the sensor measures a force, a distance or a combination thereof.

10. The method of claim 3 , further comprising a display in communication with the sensor to display the one or more properties.

11. The method of claim 3 , wherein the chamber housing is inserted into a platform adaptor that connects the housing to the platform.

12. The method of claim 1 , wherein the chamber housing and the platform adaptor comprise a groove and tab configuration, a slot or a combination thereof.

13. The method of claim 1 , wherein the chamber housing is slidably connected to the platform adaptor.

14. The method of claim 1 , wherein the chamber housing is connected to the platform adaptor by one or more fasteners.

15. The method of claim 1 , wherein the central bore accepts a caliber selected from 17, 22, .22-250, .223, .243, .25-06, .270, .300, .30-30, .30-40, 30.06, .300, .303, .308, .338, .357, .38, .380, .40, .44, .45, .45-70, .50 BMG, 5.45 mm, 5.56 mm, 6.5 mm, 6.8 mm, 7 mm, 7.62 mm, 8 mm, 9 mm, 10 mm, 12.7 mm, 14.5 mm, 20 mm, 25 mm, 30 mm, 40 mm and others.
