i'm a big ar15/m16 fan. i have my mind set on an armalite's ar10 and ar15. i plan on using the gun for deer hunting... what i was curious was will the .223 drop the deer if the shot is placed right, will the .223 be strong enough? i compare the bullet to my 30-06 and it's a lot smaller... with the 30-06 one shot center mass and the deers just drop. only debate is that the ar10 is a lot of $$$ and out of my budget.
