Test Standards now define how many shots must be used to estimate a v 0 for the armor certification. This procedure defines a confidence interval of an estimate of v 0. (See "NIJ and HOSDB test methods".) v 0 is difficult to measure, so a second concept has been developed in ballistic testing called the ballistic limit (v 50). This is the ...
Transitional ballistics, also known as intermediate ballistics, [26] is the study of a projectile's behavior from the time it leaves the muzzle until the pressure behind the projectile is equalized, [27] so it lies between internal ballistics and external ballistics.

Bullets and casings found at a scene require a known example to compare to in order to match them to a weapon. Without a weapon, the striation pattern can be uploaded to a database such as the National Integrated Ballistic Identification Network (NIBIN) maintained by the ATF or the United Kingdom's National Ballistics Intelligence Service ...
Krupp armour was swiftly adopted by the world's major navies; ballistic tests showed that 10.2 inches (25.9 cm) of Krupp armour offered the same protection as 12 inches (30.4 cm) of Harvey armour. Krupp cemented armour
By Lidia Kelly (Reuters) -Russia is boosting its ballistic arsenal with new strategic missile systems, plans maximum-range launches and may increase testing in response to growing external threats ...
Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration.
Photo of synthetic ballistic gelatin showing terminal fragmentation of a .243 projectile. Ballistic gelatin is a testing medium designed to simulate the effects of bullet wounds in animal muscle tissue. It was developed and improved by Martin Fackler and others in the field of wound ballistics. It is calibrated to match pig muscle, which is ...
