At first I thought this topic would have pictures or something
A .243 is a good deer rifle, nothing wrong with what you are shooting at all. You also have to ask what type of action are you more partial to, pump,lever single shot or bolt action. Then we may be able to recommend a caliber. Also if you are a more petite girl you may not want to lug around a heavier rifle, plus it will hinder your acuuracy while trying to steady on your target. I myself like to still hunt for hours on end but I also am not affraid to walk either. A heavier gun will wear you out while walking. And hunting is not for the impatient, especially these days.
Take a look at this rifle it may be something to look into.
