A multiple stage pyrotechnic shell apparatus is disclosed. The invention has enhanced efficiency to increase lift and reduce the risk of one or more of the charges from exploding near the ground. The enhanced efficiency is obtained through the novel use of shaped breaks that conform to the shape of the inner surface of the shell's launch tube, and in particular through the use of cylindrically shaped breaks in round launch tubes. In addition, the present invention further enhances efficiency by configuring the breaks such that all the breaks weigh the same or the upper breaks weigh more than the lower breaks in the launch tube.
