Howdy
About ten years ago, one of my pards in Cowboy Action Shooting married his girlfriend at a big CAS match. She was a CAS shooter too, as was her Dad.
A bunch of us in the wedding party got all duded up in our Sunday best, and of course we were all carrying our single action revolvers. In addition, a bunch of us were carrying our shotguns, making it a true shotgun wedding. After the ceremony, we all fired our shotguns, loaded with black powder blanks and confetti, into the air in celebration. Everybody had a good time, except for a few guests who were nervous around 'all those gun people.'
Unfortunately, the couple divorced a few years later, but we all had a good time at the wedding.
