6mm Grendel?

[ducks-and-bucks]

Any built a 6 Grendel?? Im kicking around the idea... i have a 6.5 grendel that shoots amazing... case capacity wise and given the performance of the 6.5 a necked down version to 6mm would probably kick ass... just guessing it would probably be about 300 fps faster given the smaller bore and smaller bullets... and i think iyd be a tack driver too.... what yall think?

I just built one, it is an arp barrel. it is going to be a shooter from the looks of the break in shots.

taking it out next weekend to see what it has. I am expecting .5 moa or better. here is a pic of it

If a 6MM is what you want Black Hole can fill the bill. Obviously not a Grendel but we have them shooting in the 2's and 3's. I have three AR's in the 243LBC and a 26" Savage BHW barreled that is slated for use in my F-CLASS 1000 yard gun.

DaB:

I have been shooting a 6mm AR for five or six years now in High Power. Size down the Grendel brass, load and shoot. H-4895 does the trick with a 95 or 107 Match King. Far superior at any distance to the 6.5 version. Downside is that you need to be more careful about loading or you will get into trouble with pressures and you will go through barrels much faster.

where do you find a good barrel chambered in this? I run a satern barrel in my 65 grendel, and that barrel is amazing! If I did it I wouldnt want a cheap quality barrel... I've been real happy with satern, but they are a long wait time out to get anything from them...

[BluntForceTrauma]

I'm gathering from his 6mmAR website that Robert Whitley only sells uppers, but maybe he has a lead on barrels, as well?

As glshooter pointed out on another thread, Black Hole Weaponry provides such a barrel, as the 243 LBC. I have two (one in 223 and one in 264 LBC), and both are excellent barrels. A 3p polygonal bore, they have a reputation for running a tad faster than a conventional rifle cut bore, and are exceedingly easy cleaning tubes. Both of mine are quite capable of sub .5 MOA accuracy.

Interesting round , this is. ,-
Anything new on the .257 Ted? BTw? It's a variation on the Grendel case also.

[PrecisionFirearms]

We would be willing to make barrels. We would need at least 5 barrels to do a run.

We have in stock 6mm Barrel Blanks from Bartlein which we normally use for 243 Win in AR308 Platforms.

Price - the same as 6.5 Grendel.

Lead time would be dependent on Reamer Arrival.

One of my short magazine lenght loads that I shot early on in working with my 243 LBC I load it a bit longer and hotter in my F-Class 500 yard loads.

A guy next to me shot a 6mm Turbo (6mm in a Grendel case) at 1,000 yards with iron sights. He did very well.

[SG4247]

I have a couple of 6ARs.

One is a special "tight chamber" for Lapua Grendel brass only. The other runs any Grendel Brass. I personally own both reamers.

Working on load development for the tight chamber gun now. Very pleased with the velocity and accuracy so far. Shows alot of potential for fast MV.

I can re-size the Grendel brass necks in one shot, using a special 6AR Redding die. No fire forming or other special tools needed.

Very pleasant to shoot also. Targets are both shot 105 grain class bullets, Amax and Scenar.

wouldn't a 6mm grendel pretty much be a 6ppc? wasn't the grendel basically a 6ppc necked up to 6.5?

[SG4247]

The 6AR continues to amaze me.

Quickly becoming my most favorite gun in the safe(s).

Thinking about building more of them!

I'm also thinking the 6.5 Grendel case design accommodates the .243 bullet really really well.

The Grendel and 6mm AR have more case capacity because the shoulder is blown forward.

[hydrotech]

The Grendel and 6mm AR have more case capacity because the shoulder is blown forward.

ah i see the shoulder is moved forward. Is this image an optical illusion? It appears the 6mmAR has a longer coal than the 6ppc as well. bullets seated out farther?

[SG4247]

In my case, I just size the standard Grendel case neck down to 6mm using a 6AR die from Redding. It does the operation in one step, so its very easy.

The 6AR Turbo and FATRAT both have the Grendel shoulder blown forward even further than the 6AR, so they hold more powder and have more MV potential.

In all cases, we are constrained by the AR-15 magazine length, so overall length is 2.250"-2.260" maximum for the 6AR, 6ARTurbo and FATRAT.
