I think it depends on the circumstances.If you already owned one and that was the only rifle you had to use and you were goin to shoot in the clear open then I would say yes if you are profeciant with it.But no if you are goin shoppin for a strictly deer rifle.Just my .02.
Shot my first buck/deer through the heart with a .222.
I didn't hit mine there, but it was a very sick dieing deer when dad finished it off, that was back in 1957. Killed one with a 22-250 back in the late 70s or early 80s. That one was shot through the heart.
The way that you wander is the way that you choose,
The day that you tarry is the day that you lose.
Sunshine or thunder, a man will always wonder.
Where the fair wind blows.
I've taken MANY deer with my ol' Win. Model 70 223.
With a smaller cal. shot placement certainly becomes more critical,get to know your firearm and it's limitations(as well as yours).
I've since realized I needed something bigger,
now I knock'em down with a 22-250
I killed a Deer years back with a 223 Rem. and a heavy handloaded Win 64 gr Powerpoint bullet.Did it kill the Deer? Yes. Would I buy or recommend a 223 Rem as a Deer rifle? No Way. To many other cartridges much more suitable out there. I would set the 243 Win. as minimum.

i knew a NY game warden that would hunt late season, in deeper snow, with a .223 in a HK semiauto sporter rifle. Very selective with his shots, but he would drop them nicely (according to him, and he did not b.s. very much).
