IIRC, 2,550 is an easy number to get out of a 16" Now all we need is poison-tipped 224V ammo. . |

A beautiful range day. The only bad thing was I didn't take along my other lowers, just didn't think of it.
With the 3 ounce buffer, the .224V ran just as poorly as with the heavy buffer. Getting three consecutive shots without a jam was a rare treat, and with both the TMJ and the GMM ammo. If I'd had another lower I could have swapped to test. Bad miss. No misfires this time, so the firing pin change may have helped. The top cartridge always loads from a bolt release, but after firing many partial feed jams occurred with every magazine (PRI and AR Stoner). The top cartridge was partially pushed from the magazine, then the bolt over-rode it and hung. A number of rounds were gouged so badly, probably by the bolt lug, that I could not trust them for firing (some wouldn't even chamber). And the shoulders were dented. One of my coworkers has a 6.8 rifle so I'll be able to borrow a couple of his magazines to test. And I'll take my UU small frame lower and the BuildAR lower to the range next time to try eliminating other possible causes. Anything else worth looking at? Given the disruptions I didn't try shooting for a group posting here, but the three shots that worked without clearing a jam in the middle all fit in a 1/2" square. The rifle is going to be accurate. |

Blew off the last day of housecleaning (sorry dear!).
The .224V upper worked perfectly on a different old lower (Roggio Arsenal, go ahead and laugh; its all I could get at the time, it was one of the OK ones, and it worked fine on the LaRue Stealth upper). Bolt always held back on the last shot, 100% feed with both the 75gr TMJ and the GMM factory ammo, using the PRI or AR Stoner magazines. I was also going to test it on my BuildAR lower (RO) but could not get the 224V's Aero Precision upper in; the rear lug is too tight, and I didn't have a way to apply more pressure at the range. The BuildAR's own RO upper is also a very tight fit. The Anderson lower from the 224V worked on my LaRue stealth-upper (AIM BCG, LaRue 5.56 stealth barrel) with one issue. With the bolt forward the magazine would not fully seat. Didn't matter if you whacked it in, until you did that with the bolt retracted it wasn't all the way locked in. The top round would not feed if you inserted and popped the mag with bolt closed then used the charging handle, and you could feel a slight movement and click when finish-seating the magazine with the bolt retracted. That happened with both the PRI and the AR Stoner 224V magazines. That did NOT occur with the Roggio lower on the Stealth upper or the 224V. So, out of spec lower that just didn't work with the Aero upper? Problems with magazine catch or bolt catch or both? Thanks |

Went for another quick range trip with the Larue .224 Valkyrie. Shot some factory rounds and reloads through the chrono as well. Velocity is below. I think federal AE went a little hot on these because I’m getting over their stated velocity and this is a 20” Larue compared to published velocity is from a 24”. I also only had 3 rounds of American Eagle left and shot a .4” Group!!. FGMM 90SMK not so good around 1.5”-1.3 today. Also two different lots had 100fps velocity difference and the faster was blowing primers. Anyone else expierence blown primers or significant velocity changes lot to lot? I will post load data once I find some good loads.

Quoted: About 2 months ago, while I was there, a guy came into the LGS where I'm on a friends basis with the owner. The customer was complaining about having just purchased a 224 Valkyrie AR15 (it was a Savage, as I recall) and it was spitting primers out of the cases like mad. The LGS owner and the customer were stumped until the next day when they talked again, having read the same article online in the interim: apparently, there was a batch (or two or more, I don't know) of Federal 90gr 224V ammo that was blowing primers. It was the ammo, not the firearm and changing to another Federal cartridge cleared up the problem, they reported after the ammo was switched. Maybe they have the same problem in other weights. Maybe the ammo in question here is simply older (original) stuff working through a slow vein of the supplier channel. --HC View Quote |

I was finally able to get to the range with my 224V yesterday. Unfortunately I ended up only having 20 minutes of range time and only shot about 25 rounds. My first shot from 100yds was on paper and a couple rounds later I had it pretty much on. I was running out of time and rushing so I have no real groups to post. I had one five shot group with three rounds touching with the other two opening the group to 1 1/2 - 2” inches. I was shooting 90gr SMKs. I had three incidents where a fired case ejected but the bolt did not strip a fresh round from the mag. I was using C-products mags I had laying around for my RRA 6.8SPC. I have a couple PRI 6.8 mags I will use next time. I’ll try to get back to the range next week and hopefully be able to settle in and see how it groups.

Hopefully it's not off topic, but I was wondering if anyone is reloading 224 valkyrie for their LaRue stealth barrel. Does a regular full length die work or is a small based die needed? Maybe @LaRue_Tactical would be able to assist with this question.

Has any one here had experience with Hornady 88gr ELD match. I went to the range yesterday with some Federal 75gr and some of the Hornady 88gr. My rifle is built on a ultimate upper so it is all Larue and i was using a 10 round pri mag. The Federal shot good sub 1moa function was perfect. Then I switched to Hornady first shot was always fine but feeding was a issue with the second round. Did not matter if the mag had 3 rounds 6 or 9 same failure. One round in the mag is how i ended up shooting the Hornady which shot approx 1/2moa. Also the bolt would never hold back on an empty mag withe the Hornady. Since the Federal shot fine is this a issue with my Hornady ammo or does my buffer need to have the weight altered?
|

[#35]
The horndady didn’t seem as hot as some others. If you are using the white sprinco spring try changing to a standard mil spec spring. I had a similar issue it wouldn’t lock back so I switched the spring and no issues.

The best factory round I have found so far has been the Hornady 88ELD. Below are a few groups. Another positive note is I’m getting on average a velocity of 2735 FPS!! From the 20” LARUE. Hornady ammo list 2675 FPS from a 24” test barrel. Bottom left group was a different load I was working up. This thread needs way more groups posted.

My 100% Larue 224v is getting blown primers in federal 75 and 90gr suppressed with tranquilo and unsuppressed. After several months: Federal tested the ammo(75 and 90gr) I sent back to them and say all good, Larue disassembled the upper, cleaned and reassembled and said it test fired without issue. I have yet to test it after coming back from Larue and I have not tried hornady ammo yet either... I'm just at a loss. Larue did say they cant promise 224v will function 100% suppressed. But I am experiencing a 30-90% blown primer rate regardless of suppressor(tranquilo) use.
Fyi: 75 gr got excellent accuracy (.5moa) but horrible blown primer %. 90smk was less likely to get blown primers but 1.5-3moa. |

I have over 200 rounds of Federal 90 gr through my LaRue Valkyrie with no blown primers, cratering or other signs of high pressure. No experience with the Hornady yet. Can’t wait for Redding to release their S bushing neck sizing dies for Valkyrie so I can start reloading. Was told by factory they would be released end of July or first part of August, but haven’t been able to find them yet.

My first email back from the motherland: we have been working with Federal regarding ongoing issues that we are seeing with their .224 Valkyrie offerings. We will be happy to bring your upper back in for inspection, but we cannot guarantee at this time that it will function reliably suppressed. We have also experienced issues with their recommended alternative ammunition to the 90 gr. GMM load… and the response we most recently received from Federal was “thank you for your input.” Several other manufacturers are experiencing similar issues. Thank you for your patience thus far.
V/r John I suspect it is the ammo, even though federal has tested the lots I've used. Ejecting around 3. I'm glad others are not experiencing this, at least on the forums. I'm going to snag hornady and other lots of federal next chance I get. |
