Rifling, which can be one of numerous types, will be cut with either a left or right hand twist, determining whether the bullet will spin clockwise or anticlockwise. The location of the peak pressure and the shape of the pressure curve is determined by the burning characteristics of the powder used and the loading density.

For more information see this topic. During the initial examination of a firearm, a number of details should be noted. Investigating The field of ballistics is able to identify rifling patterns, marks made by using suppressors silencersshell casings, powder burn and many other different areas relating to the use of firearms and the evidence they leave behind.

Ballistics is the field of mechanics that deals with the launching, flight, behavior, and effects of projectiles, especially bullets, unguided bombs, rockets, or the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance.

A ballistic body is a body with momentum which is free to move, subject to forces, such as the pressure of gases in a gun. As a supplement to our Online Ammunition and Ballistics Catalog we have included our Interactive version for download. The study of firearms and firearm ballistics is often divided in internal, external and terminal ballistics.

Internal ballistics refers to the processes inside the firearm, the minute space of time between the shooter pulling the trigger and the bullet exiting the muzzle of the gun.
