Trajectory Plot 2.5 Description

"This program calculates the trajectory of bullets along a flight path."

BSEditor: Based on the Gavre (G1) functions as described in Hatcher's NoteBook (chapter XXIII), this program calculates the trajectory of bullets along a Flight path. This program deals with exterior ballistics only - that is, the path of a bullet after it has exited the muzzle of a firearm.

Since one often works up loads and practices with firearms in moderate to warm conditions at relatively low altitudes, and then hunts in typically much colder temperatures, and sometimes at high altitudes, this program is designed to help one in predicting the field results based on range observations. Looking at it another way, this allows one to define the desired field results and then learn how to adjust the firearm under range conditions in order to obtain those desired field results.

Caution: Exterior ballistics is not an exact science. Wind drag is a long studied effect, yet has proven itself to be (so far) impossible to describe in a single, definitive formula, especially around the speed of sound. Hence, the trajectories presented by any source are at best an approximation.

Most programs/books are based on table look-up routines. This program uses the Gavre functions to calculate the deceleration of a bullet over it's flight.

In it's simplest form, given a bullet, it's muzzle velocity, the "scope height" of the gun, the environmental conditions, and the desired radius within which one desires the bullet to remain, the program calculates and displays the bullet's trajectory, the maximum point-blank-range, and the bullet's "drop" at 25, 50 and 100 yards.

Other features of this program:

* In addition to the Gavre (G1) drag curve, Krupp curves and modified Mayevski drag functions are selectable.
* Independent environmental conditions can be specified for the range and the field.
* Tail and cross wind can be specified.
* Bullet drop and energy are displayed in graphical and (optionally) tabular form. you can free download Trajectory Plot 2.5 now.
