I would go for a 357 Maximum or a 444 Marlin chambering. The 45-70 would work as well. There is nothing wrong with the 357 or 44 Magnum however.
Ohio law says the chambering has to be in a handgun with at least a 5 inch barrel shooting a straight walled cartridge. It doesn't have to be a handgun cartridge.
Thanks for clarifying.
The Max is a nice round, one worth considering, with the only issue being ammo availability. I do handload, but it's nice being able to just walk into a store and get ammo if needed.
I think any of the rifle based rounds, like the 444 or 45-70 will be WAY more than I intend to shoot. I don't see me even trying to shoot a deer beyond 100yds with a handgun at this point in time.
I have a Ruger in 357 and I know first hand how little of a twitch it takes to miss a fair sized target with a handgun.
To me the 44 Mag or 445 Super mag, or 357, 360 Dan Wesson, or 357 Max is about tops for the strraight walled rounds. MAYBE the 460 S&W but I don't think a Contender can handle that round, not sure.
