Not really... I have an antique Winchester 10 Ga. Salute Cannon:
It makes a great BIG BOOM! producing lot's of white smoke from the black powder blank shells.
It's great fun on New Years' Eve as well...
One year, about 30 years ago, when we were living on a court, all the neighbors in the court had a 4th of July block party. We blocked off the court and were shooting off our safe-and-sane fireworks and I had my cannon. I pulled the lanyard, firing the cannon toward the entrance to the court... just as a Police car turned on to our street! Lucky for me the officer was one of my customers at The Old Sacramento Armoury, the gun shop I managed.
Looking for a picture for you, I just learned they are being manufactured again and are again available for sale! $525.95 at the Cannon Store. Amazing.
Mine's an antique.
