7.62 Grendel? - apynckel - 03-06-2015

Anyone seen this yet? Someone is necking up grendel to .308 and supposedly getting decent results...

*edit* This article is from Dec 2013, so probably already posted a gazillion times. If so, my bad.

Some competitors on the AMU teams were using something similar a few years back. What I saw they were calling it a "30 Grendel".

I think the 7.62x39 thing might catch on though! : )

7.62 Grendel? - sneaky one - 03-07-2015

.30 Major was the name. There is a .257 Ted out there, and a 6mm AR Turbo, from Robert Whitley.

Funny, nobody tried a 7mm version yet. Jasmith has a .20cal version.

I went the easy route on my lil .30--7.62 x 40 WT. It's just a tic slower than the .30 major, works great on deer.

Was the Grendel not developed from the 7.62 x 39?

So what is the difference between the 7.62 x 39 and this 30 ARX?

Strictly speaking, no.

6.5 Grendel was developed from the 6.5 PPC, which was developed from the 6 PPC, which was developed from the .220 Russian, which was developed from the 7.62x39.

What about the 2nd question?

7.62 Grendel? - dmsims21 - 03-07-2015

I'm guessing, but the 30 ARX probably has a straighter wall so it will stack right in an AR mag.

I don't know the answer to it. Have you googled ".30 ARX"?

I thought they were calling it the 30 Gremlin.

30 ARX has straighter walls. More capacity. Runs at higher pressure. Uses a real .308 bullet. Feeds more reliably thanks to the lessened case taper. Case is slightly shorter on the 30. It has gone by at least five names/variations.

Ohhn one other thing. I have one coming as soon as I pick up a FF tube and gas block. I also have a custom bushing die. I'm excited.

And then there's the .308 arrow. Hornady cases marked .308 arrow, and uses AA bolt. Interesting round.

I have never heard of them, that is interesting.

So is this a 6.8 REM necked up to a 30 cal?

7.62 Grendel? - Bwild97 - 03-10-2015

The AA bolt would be too large in diameter for the 6.8 case.

7.62 Grendel? - GLShooter - 03-10-2015

30 ARX, 30 Major, 30 Walker, 308 Arrow, 30 Grendel, 30 AMU and a coupe others out there. I don't know the name of it but a world record benchrest group is held by basically the same thing. It is doing very well in score matches in BR also.

The AMU prefers it for the long range 3Gun stuff. It shoots MAJOR and this is the big benefit in that venue. I'll probably shoot mine a bit there but just like shooting th 6.8 varaints the brass is not cheap and you hate to leave it on the ground. I do like my Lapua.

No, it's a Grendel necked up.

Ok. So if a 30 ARX and a 308 Arrow are both necked up from a Grendel, what is the difference between the two of them??

Probably nothing to speak of. A 0.001 here or there but I'll bet lunch you can load either one with the same dies just like the G. and the 265 LBC. Hornady makes the Arrow dies and they are proprietary.

+1. Prolly the only difference is mfr. haven't measured the 30arx, but the two are very similar.
