BAAAD practice to shoot over open water like that.
And he’s a wuss. ANYBODY can hit a target as big as a case! Set out individual cans and make it sporting.
And for God’s sake shoot with a proper backstop.
You have a good point, when shooting I always want the spent projectile to land in a dirt hill behind it.
But on your second point, this guy was not in any marksmanship competition, but making a political point in a dramatic way that gets attention and brings his point home.
As for shooting at cases instead of singles, he got to show off his full-auto.
But, every thread needs a Karen. Congrats.
