Unprimed Brass Cases
.224 Valkyrie (Small Rifle primer)1.588 - 1.592 O.A.L.
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.
*Starline Brass does not sell any loaded ammunition. What you are purchasing are brass cases only and will need to be loaded into ammunition in order to be fired from a firearm.

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.
