224 Valkyrie...newest AR cartridge from Federal

[Waylander]

Re: shorter barrels 16" and below in .224 Valkyrie

This has me interested in converting over from 6.8 SPC to use my LWRC 6.8 specific receivers and mags.

#1 6.8 brass seems to be drying up and when you can find it is over 35 cents per case.

#2 Federal 75gr FMJ .224 Valkyrie ammo is less than $10 per box at Walmart.

Out of a 24" you should be able to push 80gr ELds to 3000fps with 25gr H4895. With the velocity you can get out of the 88s, 90s and 95s they will not catch up to the 80s. The 80s will have less drop and drift and they are easier to find an accurate load for. If the X-caliber has a SAAMI length freebore try the 80s around 2.285" OAL. There are some new bullets in the works for early 2019 but we can't say anything specific yet.

Thanks for the help.

Definitely going to try this cartridge, but I am holding out for the LWRCI 20" DI Gun. To me this just makes a lot of sense, since this platform was custom designed for 6.8 SPC and has the PMAGs and custom lower receiver etc. (and no, I have no affiliation whatsoever with them. Never even owned one).

Has anyone heard anything about performance from this rifle?

I was planning on buying a seekins 224 upper for shooting prairie dogs, until I saw the numbers for lighter weight projectiles. It seems the only real advantage over .223 is with the longer heavier bullets that have to be single fed with an AR, which I don't use on varmints. If this cartridge could get a 60gr nosler out the muzzle above 3300 I'd be all over it, but all the load data that I've seen lists around 3100 max, which I can already do with .223 at 5.56 pressures.

Might be able to do that with a .22-250 barreled AR10.

22-250 will definitely do it, but that entails building a entirely new rifle, vs a upper swap. I'll do it eventually, just not a priority this year.

Don't believe the books or BS. The lawyers have those books watered down. 80s will do 3000 out of a 24" barrel. 55s will do 3400 and 60s 3350. Try stick powders between H322 and H4895 You should top out around 27-27.5gr.

This is an article with James Gilliland that just came out about 224 Valkyrie...interesting discussion and he mentions 3 new loads from Federal coming later this year perhaps.
