mainly we hunt rabbits(cottontails and snowshoes) on the river bottom, knee high grass/wheat/corn, brush piles, irrigation ditches full of cattails, chest high sagebrush...........few rabbits out on the short grass prairie, mainly jacks and best way to hunt them is via spotlight at night while they are out in the open feeding.
a 22 works just fine in high grass and such if yah know their habits..........unless your close they tend to stay put, if you can see them you can hit them with a .22. after a bit of hunting them you tend to know where they are likely to be sitting, watching for preditors......you quit looking for rabbits and are instead looking for spots that they are likely to be sitting. i dont know anyone up here who uses dogs, few use shotguns unless they happen to jump one while bird hunting.
