Clear Ballistics (Permagel)
Definition
A synthetic polymer-based ballistic test medium formulated to match 10% ordnance gelatin at 4°C. Optically clear (allows high-speed video of bullet penetration), does not require refrigeration. Calibrated with the same FBI BB drop test. Not formally recognised as a substitute in official FBI or NIJ testing but widely used in research and demonstration.
