Personally I dont hunt deer with a .223. I think my 6mm Remington is abit marginal to maybe. I use a .270 or a crossbow. That said I have read alot about guys south of the border who shoot deer all the time with a .223 where in some places the deer are smaller.
6mm marginal? .244? c'mon. I've harvested 1 to 2 deer per year with mine no problem up to 250 yds.
6mm and .270 fly in the area of 3000 fps and both have in the area of 1400 ft/lbs of energy at 300 yds with a 100gr bullet.

What's the difference. Why don't we start another 30-06 vs .270 thread.
BTW. .223 is fine for Whitetail, except it is illegal in Sask.
