This cartridge can be fired from all types of 12 Bore guns having 70 mm or more chamber length. This is generally used for scaring away of animals, protection of crops and hunting. Smokeless propellant powder and non-corrosive caps are used in the cartridge. Use of hardened lead shots gives a good impact on the target.
