2. or power charge in a cartridge is
the propellant which, when ignited
by the primer flash,is converted to
gas under high pressure and
propels the bullet or shot charge
through the barrel and to the

5. Two types of gun powder
Black Powder - is the oldest of the
propellant
• Consist of irregular grains that have either
dull or shiny black surface
• When fired it produces large volumes of
grayish smoke and considerable residue is
left in the barrel
• When ignited it also burns quite rapidly

6. Composition of Black powder
Potassium Nitrate 75%
+
Sulphur 10%
+
+
Charcoal 15 %

9. Smokeless Powder
• Most powerful of propellants
• Does not give off huge cloud of white smoke
unlike the black powder
• Used in rifles,pistols and revolvers by
forming dough into sticks or grains
• Grains can be found round the entrance of
the wound
• once ignited, will burn rapidly and vigorously
until they are completely consumed.

10. Composition of Smokeless Powder
Nitrocellulose ( Single-base
powders)
Nitroglycerin ( double-base
powders)
Nitroguanidine ( triple-base
powders)
