Filed:

Nov 1, 2004

Appl. No.:

10/980107

Inventors:

Michael Stock - Maryville IL, US

International Classification:

F42B 5/26

US Classification:

102464000

Abstract:

A shellcase body for use as part of an ammunition cartridge, which includes a base portion at one end, a middle portion having a substantially straight sidewall and joined with the base portion, and a shoulder portion joined to and extending from the middle portion. A neck portion may be joined to and extend from the shoulder portion. The shoulder portion is typically annularly shaped and includes a semi-circular sidewall that extends between an aft end and a fore end. The semi-circular sidewall has a curvature that is defined by a circular arc having a predetermined radius and a center that is positioned a distance away from the shellcase body center longitudinal axis. The shoulder portion is joined with the straight sidewall at a secant point of the circular arc, i.e., the straight sidewall defines a secant line that intersects the circular arc at the aforementioned secant point.

Michael Stock - Maryville IL, US

International Classification:

F42B 10/00

US Classification:

102508000

Abstract:

The present invention is a controlled expansion projectile () having a bonded rear core and includes a metal jacket (), a dense core (), and a tip (). Metal jacket () includes a nose portion (), a middle portion (), and a heel portion (). Nose portion () includes a front cavity () and heel portion () includes a rear cavity () defined by sidewalls (), an open end (), and heel (). Dense core () is typically formed from lead but may be formed from lead compounds or other heavy metals. Dense core () may be enclosed in rear cavity () using a closure disc () joined with heel () to seal open end (). Dense core () is joined with sidewalls () thereby forming a bond (). Bond () may be a metallurgical bond (), a mechanical bond (), or an adhesive bond (). Tip () is at least partially inserted in front cavity (). Sidewalls () of rear cavity () are softened during either a metallurgical bonding process or other processes.

Appl. No.:

11/512480

Inventors:

Michael Stock - Maryville IL, US
Robert Gardner - Bethalto IL, US

International Classification:

F42B 12/00

US Classification:

102473000, 102501000

Abstract:

A projectile according exemplary embodiments generally includes a body. The body has a generally cylindrical proximal portion and an ogival distal portion terminating at a distal rim. The ogival distal portion includes a distal-facing aperture extending inwardly from the distal rim into the body. The projectile also includes a nose element. The nose element has a proximal section extending at least partially into the distal-facing aperture, and an ogival distal section external to the distal-facing aperture. At least a portion of the nose element is at least partially light transmissive through which at least some ambient light is transmissible and visually perceptible to an observer.

Inventors:

Michael Stock - Maryville IL, US
Gerald Eberhart - Bethalto IL, US

International Classification:

F42B 30/02

US Classification:

102510000

Abstract:

A projectile according to exemplary embodiments generally includes a jacket with nose, middle, and heel portions. The nose portion includes a forward cavity. The heel portion includes a rearward cavity having sidewalls. A dense core is within the rearward cavity and bonded to the sidewalls. Upon upset of the projectile, the portion of the jacket forming the forward cavity peels generally back toward the heel portion thereby forming petals, and the sidewalls and the dense core axially compress and radially expand to define a bulge portion, with the jacket material substantially covering the dense core material thereby inhibiting exposure of the dense core material to the upset media.

Abstract:

An expanding bullet has a core having a proximal end, a distal end, and a sidewall therebetween. A tip is positioned at the distal end of the core, and has a generally conical distal section, and a generally cylindrical proximal section defining a proximally facing shoulder at their juncture. A jacket having a generally cylindrical proximal portion surrounding at least a portion of the core adjacent its proximal end, and a distal portion that tapers to an open end, the distal portion surrounding the distal portion of the core and the proximal section of the tip, with the distal end of the jacking abutting the shoulder on the tip to form a smooth tapering ogival surface with the tip. The maximum diameter of the tip preferably comprises a substantial portion (preferably at least about 65%) of the diameter of the bullet.
