10 ga muzzle loading shotgun my dad owned & used on geese (not a modern, nor a replica) used a wide variety of “ammunition”:
FFFG black powder, plus
1) lead shot;
2) glass marbles (kill a deer easily; penetrate 3” of hard fir at 50 yards and not break the marbles);
3) 1/4” ball bearings—with a double charge, would bring down geese that laughed at 12 & 10 gage magnums.
I would love to hear how the persecutors and judge would react to the marbles & bearings.
I’d pay to see a defense attorney put on that demonstration to this judge and the idiot persecution and then the look the judge gives them.
