In a lot of comercial shells I see what look like little stars that will softly pop out of the shell and then go zinging all over the place . Forgive me if this topic is covered elsewhere, but my searches turned up nothing. What formulas are used for these stars? As far as I know the comp is pressed in a small tube and has some sort of choke to make it fly.

I have been experimenting with small 2" shells as heading for 4oz rockets for a while now. Due to the lack of reading material focused around small shells I have done much of this experimentation on my own. Forgive me if this topic has been posted before. My struggle is simply getting a good full burst pattern. Almost all my stars blow blind. I use a mixture of bp rice hulls and a modified David Bleser flash burst. I am just looking for some pointers in the general consruction of these small (plastic) shells. I guess that's about it. If you guys have any good burst mixes that have served you well or any sugestions please let me know.
