These deceleration constant factors can be verified by backing out Pejsa's formulas (the drag curve segments fits the form V (2 - N) / C and the retardation coefficient curve segments fits the form V 2 / (V (2 - N) / C) = C × V N where C is a fitting coefficient). The empirical test data Pejsa used to determine the exact shape of his chosen ...
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 ...
C b, as a general rule, within flat-fire trajectory, is carried out to 2 decimal points. C b is commonly found within commercial publications to be carried out to 3 decimal points as few sporting, small arms projectiles rise to the level of 1.00 for a ballistic coefficient. [31]
A ballistic trajectory is a parabola with homogeneous acceleration, such as in a space ship with constant acceleration in absence of other forces. On Earth the acceleration changes magnitude with altitude as g ( y ) = g 0 / ( 1 + y / R ) 2 {\textstyle g(y)=g_{0}/(1+y/R)^{2}} and direction (faraway targets) with latitude/longitude along the ...
The QuickLOAD interior ballistics predictor program also contains the external ballistics predictor computer program QuickTARGET. QuickTARGET is based on the Siacci/Mayevski G1 model and gives the user the possibility to enter several different BC G1 constants for different speed regimes to calculate ballistic predictions that more closely ...
Figure 2: Illustration of a Rifle Showing Line of Sight and Bore Angle. This relationship between the LOS to the target and the bore angle is determined through a process called "zeroing." The bore angle is set to ensure that a bullet on a parabolic trajectory will intersect the LOS to the target at a specific range.

The principal aim of this agreement is to standardize the exterior ballistic trajectory simulation methodology for NATO Naval and Army Forces. The Modified Point Mass model [2] will be used for spin-stabilized projectiles and the Five Degrees of Freedom model will be used for fin-stabilized rockets. This facilitates the exchange of exterior ...
