First, are there any caliber requirements in your state?
I am sure many people will object, but we use 223 a lot in this state for white tail. Modern expanding bullets make this a quick killer at the ranges specified. I'll also put in a vote for the CZ-527, in that caliber or in the 7.62x39 Russian. The rifle is light and short, and the detachable magazine makes it easy to load and unload.
For heavier rounds, 243 or 260 are both excellent choices, but the weight of the rifle is a factor too, particular with smaller women who don't have the same upper body strength as men and may have trouble holding up a rifle for any appreciable time.
You didn't specify a budget. How much are you willing to spend?
