6.8 spc for hunting

[Ratdog68]

.223 is powerful enough for whitetail in those ranges.

Far from me to reccomend against buying another cartridge, but I've done the medium bore ar variant thing up down and sideways. Were I to do it all over again with whitetail in mind starting tomorrow I'd just build a light barreled fast twist 223 upper andshoot quality bullets.

I would too, IF using a .22 caliber bullet was "legal" in my State. Since it's not... well... "plan B" meant another rifle.
