Best .223 bullet for deer?

[Redram]

I have shot many deer with a 233. I have used Blackhills 68 gr reman ammo and have had lots of success. Neck shots and lung shots were the norm. Both shot out of AR type rifles with 1X9 and 1X8 bbls. I have moved up to 75 gr BTHP bullets and have been shooting hogs with them. You shoot them behind the shoulder and they run, but not that far. If you have an AR and a 10 rnd mag with the heavier bullets, you can do a whole lot of damage.
