If you plan on coming to Iowa to hunt Late muzzlelaoder it's damn cold so pack well for it the Iowa wind will eat you alive. I would Hunt Big Marsh or anything in Butler county. Iowa dnr site has a map & lists all the public land It's not very well known for it's trophy deer but that is changing & fast very little pressure on public land. I would stick to zone 7 or 10. The lower half of the state have tons of pressure & can use rifle high power. So many outfitters down that way its crazy.
