RE: girl needs help finding a gun
In my opinion the 270 is one of the flatter shooting centerfire cartridges. If you can handle it I would stick with it. Like said, you won't get any flatter or more energy farther out with LESS recoil. It just isn't going to happen.
The .243 or 25-06 are nice calibers for small shooters, but you will give up some power.
Keep in mind every gun is different as far as recoil is concerned and gun fit means a LOT. If you were to get a .270 that fit you better it might feel better. A heavier gun will handle recoil better as well. I would also suggest a good quality reciol pad, like a simms or simalar.
I pretty much agree with everything else that was said by the others.
And congrats on the deer.
