Abstract
The present invention in some aspects is directed to small arms ammunition and programmed upset characteristics thereof imparted to them using high energy beams. More particularly, the invention relates to ammunition and methods of making ammunition having predetermined patterns of engraving and/or cutting or hardening and/or annealing imparted in the ammunition's forward portion using a programming laser or electron beam system adapted for treating projectiles to effect predetermined and consistent upset configurations.

A method of forming a jacketed bullet having a front end portion, comprising the steps of:
- a) forming cup shaped jacket;
- b) providing a core;
- c) inserting the core into the jacket and forming the jacketed bullet;
- d) providing a high energy beam system capable of directing a narrow high energy beam and finely annealing and/or hardening specific patterns;
- and
- e) heat treating the front end portion of the jacket with a narrow high energy beam emitted from the high energy beam system in the shape of a first predetermined pattern onto the jacket blank wall, the first predetermined pattern being about an axis of the jacketed bullet, wherein the heat treating in the shape of a first predetermined pattern is controlled by using a control processor comprising an automated computer having storage and operator interface.
