I've got a small bag of military blanks around here somewhere if someone obtains a launcher
I know they'll shove a cleaning rod through a rabbit at 100 yards, so I imagine they'll toss a golf ball in the air too.
As opposed to aft, alee, starboard etc, though I suppose downrange would work, but may not have been a part of the vocabulary at the time.
Like arrows: one loosed them, not fired them. ('fired being a firearms term)
