Wisconsin, in the last couple years has been changing the limit, some years its one buck with each weapon bow\ml\regular firearm. This year its one buck plus as many doe tags as you want to buy (unit specific, until they sell out-not likely). Other years its shoot a doe before you can shoot a buck, we also have a dec. doe only season and ocasionally a oct. doe season.
Here, it seems to be mostly political and always completely confusing.

As to Minnesota, I grew up there hunting in Zone 1 South of Grand Rapids (HIll City). For quite a few years, we had to apply for either sex tags, other wise it was one buck only for the season no matter what the weapon.
