My girlfriend is about your size, and uses a shortened 1903 A3 springfield in .35 Whelen. It's a clean killer, and has more of a pushing recoil than the sharp punch of most high-power rounds. As long as you do the work to learn proper shooting technique, there is no round too big for you to handle, and this one isn't all that big. I always recommend medium-bore rounds for big game (generally .35 to .40), since they operate comfortably within the accurate shooting range of most hunters, and give you a little "fudge-factor" in your shot-placement. Lots of people like to talk about how they never take a bad shot, and always make clean kills with small calibers, but it has not been my experience, and I've hunted with lots of these people, tracked their wounded deer for them, and heard all about how it wasn't their fault. Hunting never presents a perfect shot, so I don't recommend that anyone plan on it. Make sure you use enough gun. I'll note that the deer where you live may not be as large as the deer where I live. Our average adult deer runs in the high 100 lbs to the low 200 lbs.
