Well if you have been here before and seen moose, why on earth would you want to use such a small caliber to kill one? Do you have something to prove? As for using a .22-250 for killing a polar bear.... as Chris Rock would say "I can drive a car with my feet, that doesn't make it a good idea". I am not overly worried about your health, I am concerned about the moose that gets hit poorly and runs into the muskeg never to be found. We are having enough problems with low populations of moose up here without guys trying to kill them with a pea shooter.
