Ohio has had a very liberal crossbow policy for 35 years; crossbows have been legal the same as all other forms of archer. I have not heard where any Buckeyes are squealing about it wrecking the Modern Weapons Season.
Just saying.
I've got a crossbow. I bought one to find out what the hoo-haw was. It worked about as well as a vertical bow-- out to about 40 yards or so. I found it clunky-- no great advantage. I'm just saying. PA deer may be more susceptible to them. I wouldn't know.
Until the last few years Ohio didn’t allow modern weapons for Deer hunting.... shotguns, if you want to consider those modern....and today only straight walled cases.
