You're in Florida. The deer are small. The .223 is a legal caliber. Pick a good bullet. Take your time and place your shot right behind the shoulder and you'll have a dead deer...
personally i don't feel comfortable hunting deer with the .223. i know it can be done. i forgot to mention that i'll also be hunting hogs with the AR15 as well. i know people kill hogs (neck shots)with lesser cartridges than the .223. but, it's not for me.
out of curiosity, what bullet would you recommend for the .223?
