I used the supplied ematch. I removed the ejection charge prior to launch. Upon ignition the unburnt grains shot up through the forward end completely deforming the 2 grain case. The delay grain was never found. The ignition pellet wasn't present after the CATO so I suspect this to be a pellet problem similar to those in the Pro38 line. The recoil deformed the bottom of the casing and the closure can't be removed.
