handirifle,
Ohio opened gun season to handguns in 1986, I got a deer with my .44mag. that year, sold my slug gun and have hunted with a hand gun ever since. The state is broken up into three zones, the zone I hunt in is in the southeast (Noble Co.) usually two deer limit, one buck and one doe, or two doe, you can only take one buck. This year we will have a three deer limit, two doe's and one buck, or three doe's.
As far as limits on handguns, it's 5" minimum bbl. length, and straight walled handgun cartridges, .357mag. and larger.
