Jeff Siewert is a retired ballistics engineer who has conducted studies on bullets, propellants, cartridge cases, trajectory matches, radar data reduction, bullet-barrel interactions (in-bore balloting and body engraving simulations), and rifling design in calibers ranging from 17 cal to 203 mm. His studies on small-caliber projectiles have included dispersion reduction on the M855A1 and M856A1; balloting and dispersion analyses for the next generation squad weapon, general purpose projectile; engraving force measurements on military and commercial bullets and studies on barrel configuration and dispersion; and case-chamber interaction studies to troubleshoot case failures. He is the 2024 recipient of the National Defense Industrial Association’s Chinn Award.
Mr. Siewert holds a B.A. in physics from State University of New York at Oswego.
