I deer hunt in Indiana, which is pretty much the same as Ohio. Well, without Cleveland but we have Gary so maybe it's a wash. Now, you can rattle on all you want about hunting the thick stuff, yadda, yadda. I've killed dozens and dozens of deer in my 63 years. Some were close in the woods, but I'm guessing more were in the open corn, hay, and bean fields.
I've got an AR in .358 WSSM. Used it to get a deer in a plowed bean field at 279 yards. Indiana basically wanted to eliminate the bottle neck rounds but we found a way around it, being the resourceful fellows we are. Sitting in the woods watching deer feed in the middle of a 20 acre field gets tiresome. Now, they're fair game.
That said, if you're gonna take that plunge better be careful. There are houses around where we hunt. You look behind first, then at the animal.
There's a reason bottleneck cartridges give more velocity. You're trying to squirt a lot of gas/pressure/heat thru a little bitty opening, pushing the bullet. If the base of the bullet is the same size as the case, the bullet squirts out too easily and you don't build pressure. Unless you know how to cheat the laws of physics, you're not gonna do a lot better than what's out there. If you believe you're gonna invent some super round nobody's ever thought of, have at it. But before you try, buy a copy of Cartridges of the World. Trust me. There's just about nothing that hasn't already been tried.
