You don't actually know much about guns do you?the ballistic being knockdown power speed and accuracy
Ok cite please?the 264 is in the Winchester book just as hard hitting and more accurate than the 308 winchester at long range another FACT.
Since when did the Army reject the .223? Im assuming you mean the 5.56.there fine calibers but the fact is the others are better and the 308 is under bore not enough powder and i think theres a reason the army rejected the 223.
