The .224 Valkyrie was introduced in late 2017 by Federal. Unlike many calibers in the past that have been a joint effort between an ammo company and a single firearm company, the Valkyrie is already being chambered by several AR-15 manufacturers such as LaRue, JP Enterprises, and CMMG as well as several barrel makers such as Satern and Lothar-Walther.

The .224 Valkyrie is touted for its long range capabilities. While not the fastest factory .22 caliber AR chambering, its short fat case allows it to fit longer, high BC bullets. This means that it can keep a 90 grain Sierra bullet supersonic to 1300 yards, with much less recoil than other calibers. AR type rifles can be converted by changing the barrel and using a 6.8 SPC bolt and magazines.

**WARNING** In firearms that use a floating firing pin (such as the AR-15 and its variants), dropping the bolt on a chambered round could lead to a slam fire. It is important that these firearms are loaded from the magazine so that the bolt loses inertia when it strips a round from the magazine. It is also important NOT to use sensitive primers that aren’t designed for use in an AR, as this increases the chance of a slam fire.

I use Starline brass in several calibers: 9mm, 357 Mag, 44 Mag, 45 ACP, 222 Rem, 5.56mm, 224 Valkyrie, 243 Win, 6.5 CM, 308 Win, and 30-06 Springfield, to name a few. I shoot steel at long-range (1000 yards), coyotes, Prarie dogs, paper and I compete in combat pistol and PRC. I've never had a brass problem with Starline brass. A few of my buddies use Lapua brass only and I have no problem out shooting them when I don't have dirt in my eyes or my power humidity isn't an issue...or when a bee stings me. Good brass!

.224 Valkyrie is one of three rifle calibers that I feed nothing but Starline. 2 are bolt rifles, and the Valkyrie is an MSR platform. I have experienced no FTF's or FTE's. Before loading, all I did was run into a .22 mandrel and deburr case mouths,with all cases usable as received. I look to Starline for brass - it is reasonably priced and of high quality, comparing favorably to other more expensive brass in my opinion.

I loaded nothing but Starline bass for the Valkyrie and have no desire to switch. The brass has held up well for multiple loadings at near maximum loads. It is consistent enough to achieve very good accuracy.

bought 500 in spring, every single one was usable and had a few extra. Very consistent weight and dimensions. Second loading primer pockets still acceptably tight, been using 80.5 grns and lighter projectiles. Noticed nothing strange. Will buy again!

I got this brass on sale, mainly because it was on sale, but since have bought more at regular price. Federal brass is lasting about 4-5 firings and the primer pockets are very loose. Nothing crazy, just moderate loadings. The first lot I still have not worn out and I have a couple groups of 20 that are on firings 8 and 9. 5 out of 5 would highly recommend. I will use them again for all my brass needs! Check us out on Instagram @imperfectliberty

I am very satisfied with the performance of this brass. I am on my third loading on the first 100. The primer pockets are not as tight as I would like, but still serviceable. I think the primer pocket is a characteristic of the round and not the manufacturing process.
