223 vs 6.5 Creedmoor advice/question for you guys?

I'm saving my pennies. My Rem 700 SPS Tac is getting a new barrel, chassis, scope in the next year. Its going to get 24" 7 twist Bartlein or proof... and I'll probably chamber in 223 AI.

I love .223s, I'd vote keep yours.
 
Basrtlein will do you proud. Don't know about the 223 or the 556 as a long range option, but am still learning. Always learning. Put a top notch scope on that AR and you might just get whatcha want. And screw dem rolling stones, if they wanna be contrary......
