FWIW, I flew a CTI M1101 a couple of weekends ago, and the pyrogen igniter supplied with the motor had cracks, and failed to ignite it, but did blow the cap off with a fair degree of authority. Did you have the cap down on the rail/tower stop or was it free to blow off? I'm not sure it's plausible that an igniter could produce enough pressure to blow off the aft closure, but getting an overpressure right at ignition also doesn't seem likely. But who knows?
