Jmb ballistics

Park Falls, WI. Nov 5, 2013. #1. Years ago I when I was on the search for a decent free external ballistics program for the PC, I came across WinBal (Windows Ballistics) and was wondering if anyone else is familiar with this program. If not, I think you can still find it online somewhere- just Google WinBal.zip and you should be able to find it.

The constant 32.2 is the acceleration due to gravity, g, and is used to convert weight to mass: Mass = Weight/g. The free recoil velocity can now be found. V F = (0.000745 slugs * 2700 f/s + 0.000177 slugs * 4700 f/s)/ (0.217 slugs) = 13.1 f/s. And the free recoil energy is given by. E F = 0.5 * 0.217 slugs * (13.1 f/s) 2 = 18.6 ft•lbs.
