I'd wear pink camouflage if that's what it took to get her out there. However, elk was the first big game animal she asked to hunt. Unfortunately she has to be 12 to chase elk in Colorado.
She might be able to handle it if I load it with magic bullets like I did her other rifles to get her to shoot them. I'm thinking a 130 grain TSX between 2700-2800 FPS might be mild enough for her in a couple of years as long as she grows into the rifle. She is 5'3" now so she'll probably make it.
