I can get over 100 shots with my BBQ ignitor they cook after a while and you have to let em cool down between shots! But I've never really had a problem.
PS I put my ignitors in the end caps so i can put fishing rods inside em when i go camping they are dule use!!

Ha, BBq ignitors. Amateurs. I have an ignition system that is obscenely complicated. I have a radio crap project box into which I have 12 volts worth of AA battery power flowing. On the box there is a safety switch, which prevent power from flowing when off, and and warning light, to show that it is armed. In the gun there are two alligator clips which will hold either a thin wire, or a smashed christmas light. Upon pushing a button, an overly powerful curent is sent through either the wire, heating and melting it, or the christmas bulb, heating it to a white hot temperature and oxidizing it rapidly in a puff of flame.

Neither filament has failed me yet.

Why thank you. Like I said, obscenely complicated, but the only times it's failed to ignite is when I overfuel it.

For my inline spray&pray it is. That was my point. I spent as much or more on the ignition system than I did on the gun itself.
