Internal Ballistics Modeling Software (DOS)

1. Leduc's Model (free)
   This model based on an empirical relation between distance and bullet velocity is useful in predicting velocity as a function of barrel length in a gun.
2. Coppock's Advanced Internal Ballistics Model (shareware)
   This an advanced analytic model that attempts to predict the velocity and peak pressure of a load given the physical parameters of the gun, powder, and bullet.
3. Other more advanced numerical models are also available.
