Abstract: A dynamic ballistic effect compensating reticle 700 and an aim compensation method for use in rifle sights or projectile weapon aiming systems 10 includes a multiple point elevation and windage aim point field 750 including a primary aiming mark 758 indicating a primary aiming point adapted to be sighted-in at a first selected range (e.g., 200 yds) and a plurality secondary aiming point arrays 760D, 760E beneath the primary aiming mark. The method for compensating for a projectile's ballistic behavior while developing a field expedient firing solution permits the shooter to express the field expedient firing solution in units of distance, (e.g., yards or meters, when describing or estimating range and nominal air density ballistic characteristics), and velocity (e.g., mph or kph, for windage hold points). Reticle aim point field 750 permits the marksman to adjust the firing solution for momentary atmospheric effects and operational contingencies such as variations in ammunition.

Abstract: The current invention is directed to a cost effective method of manufacturing bullets or projectiles for use in firearms which are identifiable after firing and undergoing damage from striking targets. The mass production of large quantities of low cost ammunition makes adoption of a requirement that projectiles be so identifiable unlikely unless manufacturing methods and costs are not substantially disrupted. The method envisioned produces projectile bodies from rod or wire stock by parting slugs, piercing recesses, inserting tags and swaging a projectile body with a wholly or partially encased identification with indicia. The stock may be extruded around premade identification tags. The tags may have repeated indicia in each projectile and some indicia may be accessible from the outside of a completed round of ammunition. The swaging process retains the identification tags which are protected by the body of the projectile for recovery after the projectile is used.

Abstract: The current invention is directed to a cost effective method of manufacturing bullets or projectiles for firearms which are identifiable after firing and undergoing damage. The mass production of low cost ammunition makes adoption of a requirement that projectiles be so identifiable unlikely unless manufacturing methods and costs are not substantially disrupted. The method envisioned produces projectile bodies from rod or wire stock by encasing identification tag material, and swaging a projectile body with a wholly or partially encased tag with indicia. The stock may be extruded around premade identification tags or a recess may be reverse extruded in each slug. The tags may have repeated indicia in each projectile and some indicia may be accessible from the outside of a completed round of ammunition. The swaging process retains the identification tags which are protected by the body of the projectile for recovery after the projectile is used.
