I don't expect a watch battery to last that long, especially if its
being used to create a spark enough to ignite nitrocellulose.

The designs I've seen place the electrode pin directly against the
primer when the bolt is closed. When the current is switched on by the
trigger switch, the current, depending on the design, does one of two
things: a) it either causes a peizo material in the primer to force the
fulminate material in the primer against the anvil, igniting the
cartridge, or b) shunts current to a spark gap within the cartridge.
