  2. Ballistic table - Wikipedia

    en.wikipedia.org/wiki/Ballistic_table

    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 ...

  3. Circular error probable - Wikipedia

    en.wikipedia.org/wiki/Circular_error_probable

    There are associated concepts, such as the DRMS (distance root mean square), which is the square root of the average squared distance error, a form of the standard deviation. Another is the R95, which is the radius of the circle where 95% of the values would fall, a 95% confidence interval .

  4. QuickLOAD - Wikipedia

    en.wikipedia.org/wiki/QuickLOAD

    QuickTARGET Unlimited is an enhanced beta version of QuickTARGET that can take several long range factors into account to make the external ballistic predictions more accurate. For this it can use several drag models; G1, G5, G7, etc. and a custom drag function that uses drag coefficient (C d ) data.

  5. Ballistics - Wikipedia

    en.wikipedia.org/wiki/Ballistics

    External ballistics is the part of the science of ballistics that deals with the behaviour of a non-powered projectile in flight. External ballistics is frequently associated with firearms , and deals with the unpowered free-flight phase of the bullet after it exits the gun barrel and before it hits the target, so it lies between transitional ...

  6. List of body armor performance standards - Wikipedia

    en.wikipedia.org/wiki/List_of_body_armor...

    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 ...

  7. Shot grouping - Wikipedia

    en.wikipedia.org/wiki/Shot_grouping

    Mean point of impact (MPI) is the calculated center of the grouping, which is the average center of all the shots, and is not necessarily located at a hole in the target. [2] The process of mechanically readjusting the gunsight 's point of aim to match the MPI is called sighting in or "zeroing" the gun.

  8. Terminal ballistics - Wikipedia

    en.wikipedia.org/wiki/Terminal_ballistics

    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.

  9. Small arms ammunition pressure testing - Wikipedia

    en.wikipedia.org/wiki/Small_arms_ammunition...

    The test cartridge must be inserted into the chamber in such a way that the hole in the test cartridge case lines up with a gas port hole that channels the gas pressure from the cartridge case to the face of the sensor. The measurement accuracy of the pressure measurements with 21st century high-pressure sensors is expected to be ≤ 2%. [7]
