AK bullet (7.62 × 39 mm) holes on 1‐mm sheet metal: A forensic‐related study in aid of bullet trajectory reconstruction

Abstract

Bullet holes play a major role in the trajectory determination of fired bullets, potentially suggesting where the shots were fired from. Few methods are currently employed to estimate the angles of incidence of fired bullets using bullet holes. The literature has stressed that knowledge about the impact behavior of the specific bullet-substrate interfaces, including the most viable method for estimating the angle of incidence of that combination, requires empirical testing to enable successful analysis.

“…A second study explored the interaction between 7.62 × 39mm mild steel core (MSC) bullets from an assault rifle and 1 mm thick zinc-coated automotive steel plates at different incidence angles [ 111 ]. Several interesting observations were made.…”

Effects of Shooting Angles and Ricochet Angles on Bullet Weight Upon Impact on Three Types of Woods (Balau, Resak, and Seraya)

“…The third specific objective was to determine the ricochet angle and the bullet weight during a shooting on different types of wood: Balau, Resak and Seraya. After the shots were fired, the ricochet angle for bullets with a ricochet effect was measured using basic trigonometry (Nishshanka et al, 2021b;Mattijssen et al, 2017). The angle measuring tool used was the Raymay Zero Base Protractor (Raymay Japan).…”
