How about a re-barrel to 400 Whelen? Shoot a cast, gas-checked bullet that fits your own rifles throat. Probably about 340 grains if the bullet was cut to fill the throat perfectly and you'd get about 2200-2300 FPS with no issues. This would do just fire for buffalo, moose and large bears, so I think it's likely to do OK for white tails too.
400 Whelen would be great, except that it's got that neck, however small. It would almost be easier to move to a state that's more enlightened than Ohio. And that would be most of them
I'm a little hesitant to go with bigger bullets (.40 & up) because I'm about to have right shoulder rotator cuff surgery and will probably have to shoot left-handed this year regardless of what I use. Not a huge deal because I'm left eye dominant and somewhat ambidextrous.
