6.5 Grendel VS 300 AAC?

[wrsteve]

Like rsilvers says they are very diffent calibers and both have their place. I have a couple of grendels but I am going to build a 300 AAC BLACKOUT 9" suppressed. It is a really great looking CQB rifle. That is the beauty of the platform - lots of different toys to build

By the way I did see a post saying that Alexander Arms was interested in the 300 AAC BLACKOUT.

Yes, here is a photo of the AA 300 BLK:

Hee Hee, Oh you did it now.LOL!

I can't read the engraving on the lower...does it say ".300 BLK"?

[Bill Alexander]

That rifle was a production standard upper with the Mk10 hand guard option but we did not get the lowers in time so the lower is a billet ambi. For production we will have ambi market forged lowers.

Barrels are 16" stainless and fully heavy fluted with AAC flash hider 5/8-24. The carrier is M16 style with properly staked gas key. Bolt is HP tested and MP inspected.

We spent a lot of time pondering this caliber and trying to decide if/where it would fit. There is no denying that there is great utility in this combination but one (the manufacturer) has to decide what the role is. In its own way it is like taking a 10.5" Grendel and shooting to 600 yards. Possible, fun, but not immensely practical. What we saw was the possibility for a light, low recoil hunting rifle. The context for us is really the lighter bullets in the 110 to 150 grain weight range. These are superb out to 200 yards and do not demand stupid hold overs. While lacking range over the Grendel it adds some cross section and as you get to +140 grains gives a capability that the Grendel cannot, without the brutal recoil of the Beowulf. Commensurately the gas system is a standard carbine length and is set for supersonic ammunition. It will be picky with subsonics unless used with a silencer.

My congratulations goes out to RSilvers for steering this caliber through the early stages and hope that he can keep it on track without the usual 47,000 variations. Alexander Arms for one will will use the SAAMI specification.

God Bless you Bill for sticking with SAAMI...and my compliments to Mr. Silvers. I already have a 10.5" BLK which I really like (as do those who I have let shoot it)...now I will have to ponder a 16".

Bill, can you shed more details on the barrel?...cut rifled?

BTW...I have a case of Hornady 300 Whisper ammo...can we start a forum area where I can complain about feeding issues?

All these cartridges have their purpose. It appears to me that ignoring the purpose behind a cartridges development, and then arguing over whether that cartridge can do some other job well, is akin to arguing about why an Indianapolis 500 car won't win at the drag strip against a fuel dragster, and then arguing over why the dragster won't win at Indy. Neither was intended for those purposes, and it is the same for many of these cartridges.

Kinda a Ford VS Chevy argument.

speaking of a 300blk if you get the chance to look at the new copy of guns and weapons , lokis 300blk is in there. Here is a link to a partial article

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

[JASmith]

...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

[bwaites]

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!

[wrsteve]

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