A co-worker got me into a discussion on the .224 Valkyrie round. At that point I hadn't heard of it. Checked it out and found is supersedes the 6.5 Creedmore and Grendel round. The round maintains supersonic speed pass 1000 yards, depending on the bullet grain. Anyone checked into this or has experience? Was about to do another build and was thinking of 6.8 spc, but after reading about the valkyrie round which uses the 6.8 mag and bolt, I looking more into it. Thoughts?
