The breech face and the striker (firing pin) of every single firearm have microscopic individualities of their own. Every firearm leaves its “fingerprints” or “thumb mark” on every cartridge it fires. The whole principle of identification of cartridge cases/shells is based on the fact that since the breech face of every weapon must be individually distinct, the cartridge cases which are fired are imprinted with this ________.

SHOT BALLISTICS – refers to the study of shots from smooth bore firearms like shotgun and muskets. WOUND BALLISTICS – is the study of the effects of a projectile on a target and the conditions that affect them. Primarily concerned with the nature and medical implications of physical injury and shock caused by bullets and explosively driven fragments. 3 Basic Kinds of Gunshot Wound (GSW) distinguished by the proximity of the weapon causing them: Contact – gun muzzle is pressed against, or within an inch or two, of the body. Close Discharge – 6” to 2ft Distance discharge – over 2 or 3 ft. FORENSIC BALLISTICS – study of firearm identification by means of ammunition fired from them.This branch applies ballistics principles to elucidate legal matters. The study of shots from smooth bore firearms like shotgun and muskets is known as ________.

Development of Firearms
- The stages of development of man's weapons are:
- Stones
- Clubs
- Knives
- Spears and darts
- Bows and arrows
- Crossbows
- Guns
- Missiles
