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 ...
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters. [2] Chg: Propellant charge, in grains; Dia: Bullet diameter, in inches; BC: Ballistic coefficient, G1 model; L: Case length (mm)
The number of units (i.e., how many bullets or shells there were per box) and packing information (i.e., whether it was in cartons, bandoleers or belts) were on the two lines below it. The caliber (CAL .45, CAL .30, or CAL .50) was painted in bold lettering in the upper left corner.

For example, the .308 Winchester uses a bullet of 308/1000-inch diameter and was standardized by Winchester. Conversely, cartridge names often reflect nothing related to the cartridge in any obvious way. For example, the .218 Bee uses a bullet of 224/1000-inch diameter, fired through a .22-in bore, etc.
Bullet parts: 1 metal jacket, 2 lead core, 3 steel penetrator. 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. [1]
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 ...
Such shots may be the result of trajectory deviation caused by unexpected changes in wind condition (known as a "wind shift" or "gust"), a muscular flinch of the shooter at the time of the trigger pull, a problem with the firearm mechanism, poor tuning of barrel harmonics, or inconsistency in the ammunition (e.g. bullet/pellet weight and ...
