I don' t believe a .223 is legal in Fla. Having hunted in Florida for several years as I remember any 22caliber bullet is illegal. Anything from .243 up to 7-08 or .270 should be soft enough for your wife with the .243, 25-06, and .257 Roberts being the softest. Stick with one of those and get her some good instruction (from another woman!!) and she' ll be fine. Florida deer are not big and are not difficult to knock down. The hogs can be a little tough sometimes. Use a premium bullet and put it in the vitals or even better just behind the ear and even the biggest Florida hog will hit the dirt.
