Excel Marksman by Hans Cronander
I am a shootist and an MS Excel professional. I've implemented R.L. McCoy exterior
ballistics in a new fashion in MS Excel. The source code includes an ODE engine based on a
Bulrish-Stoer variable step length numerical integration method for rational functions.
Anyone devoted to VBA programming is welcome to further develop these calculators, as long
as they share the improved code with the author (the 3DOF model needs to be complemented
with more retardation functions).

McTRAJ4 with
McTraj4 with McCoy original Drag Coef tables G1, G2, G5, G6, G7, GS, GL.
My RA4 was added. A new Atm10 program to calculate air density ratio.
The new RA4 table was converted from the RA4 .DCT file in Ballistic Explorer v5.5.2:
RA4 tables for the 22 rimfire are rare.

And now also smalbal2.zip.
Included in it is the original smallbal.c source and documents with
a smallbal.exe file the author compiled. He also added smalbal2.c
and smalbal2.exe, modified to include G1 drag function, paged output,
gravity turn off, Metric or English input and output, changed from command
line input to program input, and the increased max time from 15 to 150
seconds. He also included getopt.c
source.

JBM - an "improved" version
This version lets you put in BC/velocity breakpoints and the program figures out what BC to use
based on the velocity for the point being calculated. It may be more accurate than JBM's original,
if you know more than one BC/velocity pair.
The drop results are within 1% of Sierra's Infinity program for at least one long range
calculation. That difference may be entirely due to the numerical integration method used in the
two programs.
The modifications were made by Daniel Pouzzner, off JBM's code which is in the public domain.

This page started off with the kind permission of John.
He was the creator of the original collection of ballistics articles, programs,
tables and links. He needed a new home for his hard work, as he couldn't
handle the size any more, and didn't just want to discard it. Sniper
Country wishes to thank John for his offer.
