In Michigan you can only use rimfires to predator/varmint hunt at night. I've gone back and read all the reviews that have been post on here about the 17 hmr and i can't decide between the 17 hmr and the 22 mag. most shots would be 100 yds or less but i would use it for woodchucks, coons, fox, coyotes(if i see one) opposum(sp?) and maybe squirrels. what do ya'll think i should go with
