I am curious as to what some might make their igniters from and the pyrogen they use for AP motors, G and larger. I have been using leftover AP propellant from making motors, some igniter formulas have similar ingredients to propellants and some are made from a slurry of oxidizer and various fuels and metals. I some times have a little trouble with the ignition, sometimes it will start with a pop then Pffffft......ffffft....then ignite.
Another matter is the latest propellant batches using R45M are cured with a diferent Mondur curative, E-744, than I used to use and takes twice the amount to do the job (20%), maybe that is affecting the ignition properties.
