Black powder plus wad sounds like the definition of a blank to me. And it should be news to nobody, certainly not a cannon owner, that wads are dangerous within their range.
Ah yes, dat old debbil alcohol, makes you invincible and always right. Funny how the universe gangs up on you sometimes. I remember once a long time ago being extremely irritated with a car that seemed to be deliberately trying to thwart me in terms of going down the road and not hitting things. I woke up in terror the next morning but there was fortunately no blood on the bumper.
Many years and lifetimes ago I worked a season on a day sail schooner on northern Lake Michigan. It was a long standing tradition on this boat to fire off a small cannon at sunset. As the season wore on, boredom and youthful inexperience combined to gradually increase the powder load we put in the cannon. Eventually, Mr. Murphy had his day. After lighting the fuse and stepping clear, an unexpected gust of wind heeled us over, causing the cannon barrel to tilt upward, thus changing its point of aim. The wadding in the charge took out a chunk of the main boom the size of a man’s fist from 12 feet away. That was the end of the evening sunset salute for the rest of the season.
This was the start gun for the free sail races at the 100th Anniversary celebration of the Christchurch Model Yacht Club (NZ) in 1998. When they fired that sucker I think half the birds on South Island went airborne.
Just found this on Wikipedia under “Wadding”:
“The father of Robert Morris, “Financier of the American Revolution,” died as the result of being wounded by flying wadding from a ship’s gun that was fired in his honor.[2]”
Blanks aren’t harmless. Actor Jon-Erik Hexum died on the set of a TV show he was filming after shooting himself in the head, as a joke, with a 44 mag pistol loaded with blanks. Ironically, his character was supposed to be a weapons expert.
