The heaviest whitetails on record are from the Minn/Wisc/Mi UP area and some of those are listed at dressing over 300 lbs. The 500 pounder mentioned dressed just over 400. BUT most of those were from years ago. The UP of MI has changed....the deer yards aren't what they used to be due to overpopulation...our regulations for years didn't promote older age bucks, etc. They have new regs they started a few years ago so hopefully we'll see some really big boys again....if the wolves don't get them first. Stateside, Minn probably first, then N. Wisc. Some of the Canadian Provinces are a good bet too.
