all I could think of is either the MgAl isnt fine enough, bad batch of KClO4 or they havent been mixed together enough. are you using digi scales or something accurate?
try the ratio of 70/30 (MgAl 70 / KClO4 30) i know its supposed to be the other way around, but my old batch of perch used to report louder when mixed it with magnalium using that ratio. could never figure out why..
