An experimental study on the ballistic performance of ultra-high hardness armor steel (Armox 600T) against 7.62 mm × 51 M61 AP projectile in the multi-hit condition

open access: yesEngineering Science and Technology, an International Journal, 2023
In this study, Armox 600T armor steel was ballistically tested against 7.62 mm × 51 M61 AP projectile. The experimental design was constructed on the basis of the worst-case scenario which is the highest possible impact velocity in the multi-hit ...

Testing of some Ballistic Experiments [PDF]

open access: yesNature, 1901
WHEN the Council of Military Education directed my attention to the science of ballistics in 1864, I came to the conclusion that a thoroughly good chronograph would solve all practical difficulties. The newly-invented instrument was first tried in 1865 with ten screens 120 feet apart, by the ue of a 12-pr. Armstrong B.L.
