Types of fire arm weapons

I- Muzzle -loaders, loaded from the muzzle II - Breach - loaders, loaded from the breach. divided into: A- Non rifled weapons: A- Rifled weapon: most commonly used FA

Non rifled weapons : (smooth bore) 1- Sporting gun: 2- Ghaffir guns: A-Greener, B- Schneider C-Remington

Percussion cap powder shots Outer wad Non rifle cartridge Sporting gun Inner wad Rounded Shots

Sporting gun

shots

Black smokeless smokeless

Types of powders  Smokeless powder 1.Nitrocellulose 60% 2.Nitroglycerine 35% 3.Mineral Gel5%  Black powder 1.carbon 15%, 2.slupher 10% 3.potassium nitrate 75%

2- Ghaffir guns:

Outer wad Greener Schneider Remington Inner wad

Greener

Types of rifled weapons: 1-long weapons :(S rifle):  non automatic( rim)  automatic has a groove 2 -short weapons (pistol) A- Revolver:  Old (non jacketed)  New (jacketed) B- Automatic pistol. (groove)

Products of firing a gun 1- The flash of light 2- The gases 3- Flam 4- smoke 5-Unburnt powder particles  Rifled weapons bullet  Non rifled weapons Shots + wads

Estimation of the distance of firing:  powder marks 1. gases 15 cm tearing 2.Flam burn 0.5 BL 3.Smoke blackening BL 4.Unburned particles tattooing 2-3 BL

5- Inner wad penetrate body up to 3 M hits the body up to 10 M 6- outer wad penetrates body up to 1 M hits the body up to 3 M causing slight abrasion.

The shots  Up to 2 M the whole shots enter the body in one mass producing only one central hole.  At 2 M and more start of dispersion hole and few surrounding separate shots hole.  At 3 M the central hole is smaller in size with increased dispersion of shots holes.  At 4 M complete dispersion of shots holes having a circular diameter of about 16 cm.

The shots  In longer distance, the spaces between the shots are increased and the power of penetration of shots is decreased.
