In 1999, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) established and began administration of the National Integrated Ballistic Information Network. [3] In this program, ATF administers automated ballistic imaging technology for law enforcement, forensic science, and attorney agencies in the United States that have entered into a formal agreement with ATF to enter ballistic ...
Automated Firearms Identification has its roots in the United States, the country with the highest per capita firearms ownership. [1] [2] In 1993, the Federal Bureau of Investigation commissioned Mnemonics Systems Inc. to develop Drugfire, which enabled law enforcement agencies to capture images of cartridge casings into computers, and automate the process of comparing a suspect cartridge ...
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
QuickLOAD has a default database of predefined bullets, cartridges and propellants. The database of the more recent versions of QuickLOAD also include dimensional technical drawings of the predefined cartridges and for most cartridges photographic images. Data can later be imported or entered by the user to expand the programs database.
Ballistics is the field of mechanics concerned with the launching, flight behaviour and impact effects of projectiles, especially weapon munitions such as bullets, ...
The ballistic coefficient of an atmospheric reentry vehicle has a significant effect on its behavior. A very high ballistic coefficient vehicle would lose velocity very slowly and would impact the Earth's surface at higher speeds. In contrast, a low ballistic coefficient vehicle would reach subsonic speeds before reaching the ground. [75]
The gathered data regarding the projectile deceleration can be derived and expressed in several ways, such as ballistic coefficients (BC) or drag coefficients (C d). Because a spinning projectile experiences both precession and nutation about its center of gravity as it flies, further data reduction of doppler radar measurements is required to ...
Several methods have been introduced to estimate CEP from shot data. Included in these methods are the plug-in approach of Blischke and Halpin (1966), the Bayesian approach of Spall and Maryak (1992), and the maximum likelihood approach of Winkler and Bickert (2012).
