Guys, I have mixed a batch of APCP propellant today and performed a burn test of one grain (solid grain without a core) while it was wet (I mean the HTPB hadn't been set yet). I have observed almost instantenious burn of this grain, like half a second! Is that normal or it is a first symptom that there might be something wrong with the components composition?
