The VAST majority of deer taken in Iowa are taken by shotgun. There was a time that there were only archery, shotgun, and muzzleloader seasons for deer in Iowa. Maybe that has changed; however, Iowa has strongly resisted rifle hunting due to farms/ranches being of such small size--generally.For the deer hunters in Ohio, Michigan, Illinois, and Iowa it is most certainly is brilliant.
Not every state uses a 7mm Mag to shoot deer under the feeder like Texas.
