Marsh, I agree a 223 WILL kill deer and yer daughter prolly wouldn't go if she had to shoot a 30/06. My grandson started with a 223, killed a deer and hog. But it sure as hell isn't as good a deer killer as a 270W by a long shot. And in take em as they come deer hunting that 223 will let you down by wounding or not letting you take a marginal shot that a 270 can handle.

I've killed every one of over a dozen deer i've shot with a 22lr standard velocity hp, and short hps . DRT. It doesn't make a 22lr a deer rifle.

My 270W loaded with 130 gr Nosler Partitions will kill EVERY deer at any range, at any angle, any size. A 223 won't do that. Been there done that. I've seen neck shot deer with a 223 run off wobbling and need a back up shot with a bigger gun. Range was too far and bullet mushroomed against the spine, damaging but not dropping the deer.
