Same as Kyle”s Ruby Red, without perchlorate and uses German Dark Aluminum as fuel since it”s cheaper than Magnalium for me. You can use 325 mesh MgAl if that works better for you… either way use a sufficiently reactive metal fuel, if Aluminum is used add some boric acid to prevent nitrate to aluminum reaction. This mixture is a bit hard to light so a stronger prime like bp si might be needed. At least I needed several seconds with a blowtorch to light the loose composition. Will test it later on.
