6.5 Grendel VS 300 AAC?

[Bwild97]

So What role is the 300 AAC supposed to fill? And why or "how" is it an improvement over the 7.62x39?

...why or "how" is it an improvement over the 7.62x39?

One, and a major reason the 5.56 is so entrenched, is the number of rounds available in the magazine. The 300 AAC is essentially a necked-up 5.56 so the cartridge base diameter is appreciably smaller than that of the 7.62X39.

So, the improvement is "getting the same performance in a smaller package." For locales where 5 rounds is the largest magazine permitted, there is no practical difference. When that limit is not present, as in LE, military, etc. the larger number of rounds can make a difference.

Same bolt as .223
same magazines as .223
Only mod necessary is a barrel swap
uses the most abundant brass in the country
Sub-sonic loads cycle AR15 actions

Very close to or matches 7.62x39 performance in full power loads

Most abundant brass....Naw, that would be .22 LR!! LOL!!!!!

Most abundant reloadable brass? Naw, that would probably be 9mm, at least at almost every range I've been to. There are buckets of the stuff at most of them.

Most abundant reloadable centerfire rifle brass? There we go, that fits!!

Just given ya a hard time txgunner00!

The answer is obvious - build at least one of each.
