I don't mean to be stupid or dumb but, I don't get how this works. Is there a large number of guys who shoot a release autoloader? I can see chambering the first round, setting the trigger and releasing it. Shotshell goes off. But on a double target does the firing pin release on the second pull or do you pull through to set the trigger and it releases as you let off the trigger the second time? Just real curious how this works with an autoloader.
