224 Valk: Abandon ship! Starting 6.5 Gren build
I built a 224 Valk AR a little over a year ago using a CMMG 24" 1:7 twist barrel (matched with their BCG). No matter what ammo I used or what I tried, I can't get the groups at 100 yds to go below 1.5". The main purpose of this build was so I can go to the long distance range and plink at metal plates 750+ yds away. I don't see that being easily done with a 1.5+ MOA rifle. It appears I'm far from alone on this problem too. I'm seeing a lot of reports and videos saying the same thing, even when they use top of the line barrels. So, I'm abandoning ship. Selling the barrel + BCG + mags.
The rest of the rifle build is still great though and I still want to have an AR that can shoot long range. My plan is to go with 6.5 Grendel. Looking at getting a 22" 1:8 twist (5R rifling) heavy barrel from X-Caliber along with their recommended BCG. Thoughts and recommendations? Is 22" fine for long range shooting using the Grendel or should I go with 24" (nice thing about X-Caliber, I can pick whatever length I want...up to 28"). |

20 or 22 would be my choice. Good luck with the build. The Valkyrie certainly has som teething issues.

None to my knowledge. And your point is?

Hey, ship it to me(along with the bolt , of course) and I'll give it a decent burial. I finally got my "el-cheapo" 224V back from the warranty return and while it's still a bit tight, it does chamber factory loads and shoots darned good. |

You'll love the 6.5 Grendel. It's a very accurate do it all cartridge. Great on everything from 1000+ yard steel to prairie dogs to varmints to whitetail. Even a number of elk have been taken with them. Hope your build goes well!

Oh, I forgot. I'd go with an 18" or 20" barrel. But that's me. If all you're doing with it is long range steel, then you'd do a bit better with 22". So yes 22" is fine for what you want.

I hear in the end it's really Federal's fault all this crap happened with the valk roll-out, but Hornady's 88 gr eldx should get you in the ballpark with sub-MOA groups even using the long-freebore 1:7 twist barrels, though I haven't been able to verify that out to 800 yds+. Why the majority of barrel manufacturers are still pushing those is a mystery to me. I guess they decided that there is no future for the valk with 90+ gr bullets.

They like to jump from what I've read. And works with Varget. Got some ordered. |

I do have a load for a 1:6.5 barrel valk that can shoot well under .5 MOA with high velocity and energy.
Since I have the same ARP long free bore barrel and you, what was that load again (ie: bullet, powder and OAL)? I'll load something similar and try it. But getting out has been delayed due to the weather the last couple of weeks. Was hoping to hit the range this coming weekend but the forecast has changed to low 30's for my area. Too cold for me. |

I've had poor results from Varget from smaller case capacities like .223/5.56, and I bet .224 isn't immune from that. I'd recommend TAC, I ess easily get sub MOA groups with 77gr 5.56, and Valk isn't much different.
I've had great results with Varget for my .223 Wylde loads with 77 gr Nosler CC and 24 grs of Varget. .5 MOA if I skip the coffee on the way to the range. And thats with my Dillon 650. I've had similar results with TAC as well. |

I just got a notice from hornady they are coming out with new 60 and 75 gr valk ammo--probably shortish high velocity stuff which my guess would be pretty good out of just about any valk barrel.

No wonder I forget that load. I don't have that powder or those bullets.

ed: I did come up with some 88 eldx loads that shot under MOA through my "worst of the bunch" 1:7 barrels with long free-bore (which I'm guessing is most of them out there if they are still using the same chamber reamers). I purposely kept the cartridges to an OAL that would feed through conventional magazines (not the cavity back with the front cut out). Those you will have to refer to the previous posts I made, it would take me too long to track down on my computer; sorry bout that.

I'll go back and review the post. Not like I'm getting out to the range anyway with the weather we've had this winter. I may try and go on Friday afternoon if I can break away from work early. Temps are suppose to be in the low 70's.

x man on the valk forum has come up with some really good loads, though his build is also geared to pushing the COL's "out there." For the past year or so I had this crazy idea of drilling out tracks in the front of the magazine wall and into the barrel extension ramps to accommodate extra long cartridges but never did it, thinking it would be too much work and impractical. Low and behold--he had the same idea--but actually did it.

Sorry to dig up this old thread, but this still applies to it. So I FINALLY pulled the trigger on getting the 6.5 Gren barrel + BCG (4th of July sale was hard to pass up). So my next question is using 6.5 Gren ammo in magazines. Obviously using 6.5 Gren mags would be ideal. But how about standard mags or 6.8 SPC magazines (since I still have a few of those from the 224 Valk build)?

Theoretically a "good" 6.8 mag should work with the Grendel. My practical experience has been--save yourself the aggravation, bite the bullet and get 6.5 Grendel specific magazines.

I use 6.8 PRI mags. They seem to work fine. Haven't seen much of a need to buy a different mag at this point.
