Hunting moose is not a question of how far..it’s a question of be able to make a human and quick kill. The answer is how good and confident you can, under field conditions, to shoot on demand, in the vital zone, and get a hit every time ?
if you know how to hunt, you probably can get a moose in by calling it easily to 100 yards and even below. Heck, bow and arrow hunters get them in at 30-35 yards..
Long range shooting on steel plate is quite different than hunting. The moose is not painted white, and you do not choose time of day to do so
