Has anyone murdered gel with .224 Valkyrie yet?

I jumped on the bandwagon - at least as much as I can. I bought a barrel, upper, bolt, mags, and some factory ammo. I had enough spare parts lying around to complete the upper (mostly almost-new takeoff parts from various builds where someone wanted X part instead of what came on the gun). 

Well, long story short, this 22" criterion 1-6.5 twist barrel is a freaking hammer with the cheapest ammo I bought. Oddly, it outshoots the ELD-M 88gr stuff I bought by a good little bit. I have not shot anything over 1 MOA with this rifle and 75gr FMJ yet.  Not one 5-shotgroup. Including all the flyers - all under MOA up to this point.  Most significantly under 1 MOA, several under 1/2 MOA. I was shocked by this little laser beam, but have not shot it past 200 yards yet. 

So, I'm loving the accuracy, but I don't know what it would do in meat. I'd love to see what the short list of available factory ammo does in ballistic gel. Only thing I could find on the youtoobs was 60gr ballistic tip in clear gel.  

Help me obi-wan.

You shoot the 90gr Fed GMM stuff yet?  Keep hearing mixed reviews about that stuff and it's hard to nail down the truth on the Valk when the Savage guns are junk, differences in reamers and rumors of bad Federal ammo.

No 90gr Fed in stock that I could find. We have a local distributor who expects some in fairly soon. That's why I got the 6.5 twist was the issues I heard with stabilizing that round. I plugged the data into a ballistic Ap I have, and I like what I see. 

I'm cautiously excited about this. But I'm going to buy a bit of the 75gr stuff since my barrel really seems to like it.

Oddly enough, I spent several hours last night looking at what data I could find from the Google about that cartridge....I'm looking for something to serve as a general-purpose wildlife gun (deer, hogs, etc).  I have a .300 BLK and a .308 in a AR platform, but was looking for something I could put in a really lightweight handy carbine.  I started on one in 5.56 a couple years ago but it kinda, uh, got fat, and ended up wearing a heavier 18" barrel.  

This intrigues me...I'll lurk here and let ya'll spend money and then use your experiences to help me decide.  Carry on.

It fires a .223 bullet, so terminal performance will be the same as with any other cartridge firing the same projectile.  Definitely go with a faster twist.  A bonded 90 gr projectile should be outstanding.  Compared to 5.56 mm, .224 Valkyrie will obviously give flatter trajectory, less wind drift, the ability to use heavier, longer projectiles, and extend the effective range--similar to the difference between .308 and .300 WM.....

Nah the margins are too narrow...I'd say you're better off comparing it to the 260 Rem vs. a 6.5 SAUM.

The 223/5.56 is limited by its overall magazine length in semi autos much like the 260.  The SAUM solves problems by going shorter and fatter to either push a standard weight bullet a 200+fps faster or to push an even heavier bullet that wouldn't normally fit in the other load to a respectable speed.

Problem with the Valkyrie is that it must have that barrel length and faster twist rate.  An 18 or 20" 1/7 twist just ain't going to cut it.  In many cases, an 18.5" 5.56 shooting Mk262 is only going to give up 100fps to an 18" Valk shooting 75gr factory fed.  Or you can sling a 90gr SMK out of the Valk at about 175 fps slower than a 77 smk out of the above mentioned 5.56 and hope that the bullet can retain its BC advantages at those lower speeds.   If you're cool with rollin' your own and toting a 22" or longer tube...the world is yours with the Valk.

I should drive up there and shoot some of your ammo.  Got a coyote we can zap with that?

Yes. One of my adjuncts just yesterday told me there were too many yotes at his place to shoot. He has chickens and goats, so Wiley Coyote is always preset.

It's qualification season (range is booked for the ext 5 weeks straight), and I can only shoot on down time. 

I've been having short-stroke issues. Turns out my gas port should have been .093ish. It was .070ish. I got the drill press fired up and opened it up to see if it'll run better. 

I've shot it I think on three occasions now. Every time the same song. It loved the 75gr FMJ. It hates the 88 gr ELD-M.  SG Ammo down the road has a small amount of 90 gr fusion that I'm going to try out.

I plugged my numbers into a ballistic ap, ad if this thing shoots anything near as flat as the ap says, I'm going to be giddy. I just would like to see what a 75 grain does in gel. I got the idea this might be a good DM gun for some of our guys when I saw the beautiful groups (they made me cry) along with the very reasonable ammo costs.

Well, I opened up my gas port and the girl runs great now. I have only shot it out to 500, but it shoots flatter than my .308 with 168gr ELD-Ms.  2.3 mils elevation on the .224 vs 3.5 mils on the .308 (both 100 yard zero).  The .224 hits the target slightly before you pull the trigger, so it obviously is traveling through time.  That may be a slight exaggeration, but it hits the target very fast comparatively, and since there's no recoil it's easy to spot your own shots.  

I really wish I could get some ballistics gel data on the 75gr FMJ and 90gr Fusion. May be time to host a ballistics workshop for my region.  

I hope this performance keeps up. I've been very happy about jumping on this bandwagon. I need to go set up my 950yd range, but it's rained a lot and it's muddy. Plus I have to drive 20 miles. Yes, I'm that lazy.

I have to publish a retraction. I don’t think my drop at 500 is going to be 2.3 mils with the 75g FMJ. I went back to the range yesterday and shot at 100, and the 75 was shooting high. It turned out my turret had a loose screw or two. I imagine when I go back there will be more drop at 500 (I didn’t have time to go over to the range).  So I will go there (hopefully tomorrow) and find out what the actual drop is. I might go crazy and put up a chronograph and find out what the velocity is with what I have.  I might be able to actually punch in numbers to a ballistic Ap and find out what it should be doing.
