What would happen if you were to take a loaded shotgun, cock it and completely fill its barrel with something (birdshot in this case) and then pull the trigger? If you were hoping to create a mega shotgun blast that could take out an entire army of feral hogs, you’re sadly mistaken. What actually happens is that the shotgun basically turns into a shotgun shaped grenade that sends pellets flying in all directions, taking out anything in its path.
