You know, we all hear stories about deer and elk shot " in the lungs" running for miles and living for days. What a bunch of BULL!
You hit any animal through the lungs, it's going to die. Whether it's with a 223, 243, or whatever. It's going to die. It drowns in it's own blood. If this weren't the case, an arrow would never work, would it?
On that note, the 243 is a great deer round. I've had one for 15 years. And I have never lost a deer hit in the chest cavity with it. 2 bullets I use are the 95 gr ballistic tip, and the 100 gr Hornady BTSP Interlok. Had a B-T go endwise through a deer woth a Texas heart shot. Bullet lodged in the skin at the brisket. Not an ideal shot placement, but my son was young and the buck was big. Dropped at the shot.
I'd get her a wood stocked 243, then fit the stock to her. It's amazing how much less recoil is when a gun fits correctly. Trust me on this, as I shoot a 10 gauge at waterfowl. No problem.
