In the state of michigan i cannot hunt with a 38 special, or a 38-44 HD that is essentially a modern "standard book 357 magnum loading".
BUT i can legally hunt with a black powder revolver using a 44 caliber round ball.
IS anyone willing to share data results of hunting with either option over the decades? Wether its a "i loaded this here 160 swc to 1000fps in my L frame..." or "put a picket ball through a doe at 10 yards with my 1860"
