Short introduction to Exterior
Ballistics 2.5 from a user’s perspective written by Jochem Peelen:
Program has only 1.7 MB, no
installation (only unpack the zip file).
Similar to the model "Modified Point-Mass Trajectories",
Computation of the trajectory
for zero range or angle of departure:
All atmospherics conditions
(ICAO atmosphere): air pressure, temperature and humidity.
Cross, longitudinal and
Variable cross wind along
Simple methods for computation
of the bullet stability (Greenhill, Sierra, Dell).
The Most Recommended Distance
Tactical reticle computation
(MilDot, Sightron LRMOA, Leupold TMR, Vortex EBR-1 MOA and MRAD,
Nightforce MOAR, Meopta MilDot 2). Horizontal axis for the distance
or wind speed. Red cross to show where to aim:
All common drag functions: G1,
G2, G5, G6, G7, G8, GL, GS, GC, RA4, 1943 and conversion between
134 drag functions from

Coriolis force (for azimuth
and latitude, influence on the bullet drop and windage):
Program "Exterior Ballistics 2.5" is intended
and tested for Windows 2000, XP, Vista and 7. This
is a demo version of the program. Velocity in the demo
is set to 555 m/s and can not be changed. If you
have an interest, please send me your "Activation Code" at
firstname.lastname@example.org and I will
send you a file "key". Activation Code is visible after
starting the program (see the picture below) on your PC. Full version is
activated by copying the file named "key" to the program's directory (see the picture below).
