How can exit and entry wounds be identified?

• Entry wound are small and neat in most cases. But, with ultra–high velocity small bullets or bomb splinters, the entrance wound may be of the ‘blowout’ type.
• Exit wound are generally big. The size of the exit wound depends upon the shape of the local track, the temporary cavitation effect at the site of the exit, the impact velocity and type of bullet. If the missile has remained stable in the tissues, or alternatively has expended most of its energy, a relatively small exit wound results.

Handgun wounds such as revolver and semiautomatic pistol bullet wounds are very important in medicolegal practice. As the wounds caused by pistol and revolver bullets are similar, and the caliber of bullets used in the weapons are roughly the same, it should be noted that the muzzle velocities of magnum revolvers are higher than those of modern pistols.
