Given the number of folks wearing/carrying guns, for a whole bunch of years, and no loud noises from the media, I'd guess NO.
You can make a direct connection through a primer and the heat from the short-circuit will ignite the primer, but I don't really see how any "normal" static electricity could do it. All the combustibles are completely sealed off, so how could there be a spark inside the case?
Maybe, just maybe, if you put a cartridge inside a high-speed version of a paint-shaker, you might get the powder to rub back and forth and generate static electricity *inside* the case...I'm really reaching, 'cause I just don't see any other way.
FWIW, Art
