Up here in Canada when the first snowfall hits the rabbits start truning white about 10 days after and usually the snow melts wihtin a couple of days. We take our 22 rimfires and walk the thickets knowing the rabbits are white and they stand out like sore thumbs. we stalk them and when a shot opportunity arises we pop em in the head..i never hunted rabbits with a shotgun seems too simple and overkill IMO
