This guide details an experiment comparing the terminal ballistics of 9mm projectiles fired from handguns with 2-inch and 4-inch barrels, and a 16-inch rifle barrel. The experiment utilizes Clear Ballistics gelatin to visualize wound channels and expansion. The findings indicate that while longer barrels increase velocity and thus lethality, all tested configurations remain effective. Instruction is provided by an expert with high authority, demonstrating proper firearm handling and ballistics testing methodology.
