Interesting that no one has commented the fact that you get 1 antlered deer per season in OH regardless of weapon. I could be wrong, but I believe in PA you can take a buck with your bow and then another one with your rifle.
I'm guessin the average PA and Ohio hunters have a similar "if it's brown it's down" attitude. But I bet Ohio would have a higher percent that let small bucks walk, except that PA's AR require it.
I'm guessin that the percent of deer killed in PA past 150 yards is pretty low, but in Ohio it's even lower.
I'm guessin that there are probably more hunters per square mile in PA during their gun season than in Ohio. I also think the tighter access to private ground helps Ohio bucks.
Lots of guessin I'll admit. I would like to know what percent of each state's bucks are killed at 1.5 years and 2.5 years. That would shed light on if the combination of seasons lengths, weapons, antler restrictions and the numbers of hunters makes much difference in reality.
From what I know most of Ohio has better food for the deer. I do think that feeding and minerals might help a little in Ohio but not as much as a certain skinner of coons would have us believe. I also think PA went way too many years without sufficient doe harvests.
