In ohio you can only use shotgun, crossbow, longbow, or handgun with a barrel longer than seven inches and straight walled cartiges on free roam deer. You have to have a permit/ license to raise pen deer and have a high fence deer farm. At that point you can kill them with anything you want. On farms the regulations do not apply. You can do a search on deer farms in ohio and their are more than you would think in southern ohio. I seen one on the mens channel once on dish network and the guy shot a ten point buck in velvet in ohio with a 30-06. you dont even have to buy a license or tag to do it because it's not hunting, it's shooting livestock just like the farmer does or the butcher. Thats why I hate high fence farms!
