In Montana its 8/15-1/15. Early on its Antelope only in August, then elk, deer,moose,goats, sheep, bears, turkeys etc until about the end of November. Depending on the region, there is a late whitetail doe hunt that lasts until Jan.
In some regions you can shoot as many as 7 does but only one buck of either species. Elk, bear, and turkey are over the counter but the exotics are by draw. (and lousy odds I might add)
MT is pretty rough, remote, rugged, and challenging but the hunting is amazing I must say.
