Yeah, this has been cussed and discussed about a bazillion times. I remain a .243 or better fan even on Texas mini-deer. I cannot see the advantage in .22 caliber pop guns over a good .243 other than they don't chamber ARs in .243 (I don't think). I don't like ARs, so I don't care. When I can get a Remington in a better caliber for deer, why not?
I hunt my place with a .308. Now, I probably could use a .22 of some sort, but for the big hogs that roam the place. If I ever do wanna pop one of those bigguns, (I prefer ones I don't need a front end loader to get out and 200 lbs or less taste better anyway), a .223 would be totally inadequate. Oh, sure, you could "make a head shot", but I can kill 'em right there with a .308 and a shoulder shot. My deer are pretty small, but the hogs get gargantuan.
And, hey, recoil your problem? Well, there was one guy here with an arthritic shoulder and I totally understand and sympathize with that, but I know a little lady that hunts Colorado elk on a regular basis with a .338 Winchester Magnum. Hey, she's maybe 110 lbs soaking wet, and you ain't macho enough for a .243? I wouldn't brag about it, ROFL!
Yeah, with a proper load, it don't take much to kill a Texas sized deer, though, and I'm sure the .223 out to a couple hundred yards can do the job even ethically. We ain't talkin' 300 lb New Mexico mulies after all. I just don't see a real reason to hunt with such a small, marginal caliber, that's all, when I have a choice of better. The most powerful .22 I own is a .22 WMR. I don't see a reason to own a .223 or .22-250 down here where there are no prairie dogs. If I wanna hunt coyotes, my .257 Roberts or .308 will work fine, even the .22 mag at short range.
