Common questions
What does IBHVG2 predict that basic ballistic tables cannot?+
It models pressure and gas-flow gradients along the barrel during propellant burn, which lets researchers predict muzzle velocity for a given charge and barrel geometry rather than relying only on empirical firing-table data.
Would a firearms examiner run IBHVG2 during routine casework?+
Rarely. It is primarily a research and reconstruction tool used to model muzzle velocity for unusual loads or barrel configurations, not a standard step in comparing fired evidence.
