ABSTRACT:
A long-distance blast banger including a cartridge loaded with a blast banger made up from plastic material. The blast banger encompasses a sound explosives cup and a delay cup. The sound explosives cup is loaded with a sound explosives agent having components including perchloryl potassium, magnesium powder and aluminum powder. A sufficient sound value is acquired through appropriate compacting of the sound explosives cup, and therefrom realizes uniform shattering of the cup into small fragments that are insufficient to cause injury. Furthermore, at least two helical grooves extending from a bottom to a top of the cartridge are defined on an inner wall thereof, and ear attachments are configured on a base of an outer wall of the blast banger so as to correspond with the helical grooves, thereby engendering a spinning stability effect during flight time of the blast banger, reducing wind resistance, and thus increasing flight range.
