Re: legal to hunt with?
Here in Tn we used to have a rule of 24 caliber or larger but a few years back they changed it to any centerfire cartridge. I still don't think I could comfortably hunt big game with anything smaller than a .243. Although I have hunted in Al with a .223. (but they were small deer).
