Question: What is the point of having different methods of firing the guns for ballistic analysis? They've got the one where they shoot into water, the one where they shoot it into a tub of rubber balls, and the one where they shoot it into some sort of Jell-o type material.

Answer: Different calliber guns fire at stronger trajectories. A smaller calibre gun will need less friction to stop it. The Jell is used for larger calibre guns.
