He was the first person to match a bullet and a firearm with striations.
4 branches of ballistics
Backyard Ballistics was created in 2001.
Ballistics - video game - was created on 2001-10-19.
National Ballistics Intelligence Service was created in 2008.
Terminal Ballistics Research Laboratory was created in 1968-01.
The three types of ballistics are internal ballistics (study of the behavior of a projectile inside a firearm), external ballistics (study of the projectile's flight path after it leaves the barrel), and terminal ballistics (study of the effects of a projectile on its target upon impact).
Internal ballistics - Everything that happens within the rifle from the instance the primer is ignited until the bullet leaves the muzzle of the barrel. External ballistics - Everything that happens when the bullets leaves the muzzle until the time it hits the target, its path is influenced by two external forces - gravity and the flow of air around the bullet, they both charactarize so called "external ballistics".
Internal ballistics focuses on the behavior of a projectile inside a firearm, such as its acceleration and propellant burn rate. External ballistics deals with the projectile's flight path after leaving the barrel, including factors like air resistance and wind. Terminal ballistics involves the projectile's behavior upon impact, such as penetration depth and fragmentation.
shot ballistics is a shot ballistics with the study of shot ballistics lolz
striations
Yes they have Cross Striations
