This is roughly equivalent to the obsolete NIJ Level II ballistic protection level. [10] NIJ HG2 9mm Luger.44 Magnum: This armor would protect against: 124 grain 9mm Luger Full Metal Jacketed Round Nose (FMJ RN) at a velocity of 1470 ft/s (448 m/s) 240 grain .44 Magnum Jacketed Hollow Point (JHP) at a velocity of 1430 ft/s (436 m/s).
NATO AEP-55 STANAG 4569 is a NATO Standardization Agreement covering the standards for the "Protection Levels for Occupants of Logistic and Light Armored Vehicles". [ 1 ] The standard covers strikes from kinetic energy , artillery and IED blasts .
EN 1063, or CEN 1063, is a security glazing standard created by the European Committee for Standardization for measuring the protective strength of bullet-resistant glass. It is commonly used in conjunction with EN 1522 (Euronorm standard for Bullet Resistance in Windows, Doors, Shutters and Blinds) to form a ballistic classification system by ...
Historically, this table has been referred to as a "drop table." The drop table can be generated empirically using data taken by the shooter at a rifle range; calculated using a ballistic simulator; or is provided by the rifle/cartridge manufacturer. The drop values are measured or calculated assuming the rifle has been zeroed at a specific range.
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 ...
