Headstamp Marking Method

      
Application Number 17888231
Status Pending
Filing Date 2022-08-15
First Publication Date 2023-05-11
Owner US. Strategic, LLC (USA)
Inventor Blank, Michael H.

Abstract

A headstamp marking method has the steps of fabricating a plurality of inventory cases, each of them being identical with a round surface, a bare metal head, and a body, and the cases being suitable for different caliber cartridges. The method then has trimming or necking the cases, selecting cases for manufacturing into cartridges, and inscribing, via a laser inscription device, the cases upon their heads. The laser inscription identifies at least the caliber of the cartridge and the number of the cases for manufacturing. The laser inscription device, while removing material of the head along its path, attains insufficient heat and thus avoids compromising the structure of the cartridges and igniting them. The laser inscription device aims and focuses its laser upon a common plane of a head while exhausting its heat through the material ejected from the head.

Gas favoring boattail projectile

      
Application Number 17152501
Grant Number 11415398
Status In Force
Filing Date 2021-01-19
First Publication Date 2021-11-25

Abstract

A gas favoring boattail projectile has a body, a nose extending from the body as an ogive, a tip upon the nose, a meplat of the tip, a frustum outwardly of the body and opposite the nose, and a base opposite the tip. The frustum also appears as a boattail and the body appears as a cylinder. The projectile has a caliber denoting its widest diameter and serving as the basis for additional dimensions measured from it. The meplat has a proportional relationship to the boattail and the boattail has an angular relationship to the surface of the cylinder. The relationships of specific features of the invention optimize its accuracy on target while remaining within weight and other specified parameters.

Abstract

A firearm including a receiver, a barrel, a breech bolt assembly, and a trigger assembly. The bolt assembly has a bolt including a body portion, a lug portion, and a firing pin bore. The lug portion includes outward extending lugs, a cartridge recess, and an off-center hole. The bolt assembly also includes an extractor and an ejector pin. At least some of the lugs on the lug portion of the bolt have a tapering outer face so that a rearward face of the respective lug is taller than a forward face of the respective lug. In another aspect, at least some of the lugs on the lug portion of the bolt have tapering side faces so that a rearward face of the respective lug is wider than a forward face of the respective lug.
