20" upper for me with a Faxon barrel. haven't shot it as much as id like to but easy to stuff the long heavies in there.
For fun maybe, but like said you could easily pick up a 223 or 308 for inside 600 yards and almost endless combinations of bullets/powders ect at “reasonable” prices
Theres a lot if fun stuff out there for sure,,,,especially if you can get to 600+ yards on a regular basis.Looking at t.s.u.s.a. right now and theres cases in stock @ $129.90 per case of 200. 75 gr Fed.
Might grab 2 just to get it out of the way. empty em out when the time comes and I'll at least have brass for it.
Some of the other stuff I was bouncing around is out of stock.
Not that any rifles for anything are available anywhere right now, but I'm thinking .224 would offer a broader platform than the triple deuce or .22 hornet down the road. Although I'm still not opposed to either of the other 2, they're just limited to bolt guns (that I can see) and may have gone the way of the Hemi Cuda.
It is entirely possible to stuff a 90gr head in a .223, I remember those from summer league years back.
I could probably go .308, I'm sure it flies nice and straight with almost double the projo weight, but if I was looking at that, theres so many more options in that 6 to 7mm group its ridiculous.
I have no experience with 224 Valkyre.
I have searched around the internet and Wikipedia for the case capacity (measured in gr of water) of many of these other rounds one can shoot with an AR rifle.
1-I have concluded that none of them have more case capacity than the old 7.62x39.
So why don't these people creating new rounds, just use the 7.62x39 case modified for whatever caliber they want?
.224? 6.8mm? etc.
More case capacity should mean higher velocity - with all the advantages that brings.
2- Many years ago it took alot of experimenting to get my 20 inch barrel 7.62x39 AR working properly.
I did two things:
1. First I ground away the bottom locking lug to make a nice feed ramp. I had read BushMaster used to do this. However it did not yield good reliability.
2. Next I bought different brands of magazines, and found the only company that understands how to make a 30 round Magazine in 7.62x39 - that was C Products Defence.
Worked great. I had test fired many mags worth - one after the other until I couldn't hold the free-floating metal handguard anymore due to its heating up.
Always wondered if Item#1 was necessary or not.
My Lee reloading dies came with both 308 and 311 expanding thingie because many 7.62x39 barrels work fine with 308 bullets.
I think the US made barrels are tighter than foreign made and work OK with 308 bullets.
I am trying to buy some Hornady 110gr .308 GMX bullets - but they are hard to find online at this time.
3- Why start with a 224 bullet hoping it will expand to .30 or .40 ?
Start with a 30 caliber and hope it expands even larger?
4- I can't see any advantages to 224 valkyre that the high case capacity 7.62x39 brass - somehow changed to shoot 224 (and a barrel to match it) - will not do even better. Unfortunately the creators of new AR calibers just do not think of this.
That is my opinion - of course others have their own.
Who cares about the 7.62x39 case? It's problematic in the AR platform and is inherently less accurate in design than other cases.Sorry for hijacking the thread to 7.62x39.
Just think all these new cartridges should have at least the case capacity of the 7.62x39
The 223 Valkyrie comes close.
