Internal Ballistics Home Page

by Fabrique Scientific, Inc.



This page presents a summary of internal ballistics theory and offers some programs and peak pressure measuring device.

Warning: the theoretical formulas and programs presented below cannot be used to calculate loads for small arms, due to their high sensitivity to initial conditions such as the bullet pull force, chamber throat length variations, bullet engraving forces, and powder grain burn rate deterrent coatings, without verification from empirical measurements such as those presented in reloading manuals. Large guns/cannons do not suffer from the same caveats and are easier to model.
