In Iowa we hunt in areas many hunters around the nation dream of. I am blessed to hunt here every year but my main hunting ground consists of public land with about a 90/10 split between public/private. I have been hunting here for a little over 10 years now and in different parts of the state and I can say I have only seen 2 bucks that would gross 170+. I have never seen a 200" deer. A few years ago I did hear of a 200" deer killed on public by an out of state guy from Louisiana I believe. I have 3 brothers and my Dad who also hunt and between all of us I'd say we've seen 7-8 bucks grossing over 170+ but still none over 200. I run a decent amount of cameras as well and have never captured a buck over 200" on them. So I'd say obviously 200" bucks exist but they are very rare in open and heavily hunted areas. In managed large blocks of timber I'm sure there are multiple. I'm a little surprised by how high the estimates are by some of the posts in this thread. In my world I would have guessed 4-5 in the best counties with many counties having none where the habitat is lacking and gun season takes a toll on the age structure. Obviously others disagree which is what makes this thread interesting because nobody will ever know the real numbers.
