I got to shoot several of them before they were released (on game and targets) as well as being on glass for several guys pioneering them in matches. If you look at some of the first info out, Patrick Kelley was the Savage factory shooter who has been working on it, so I got some first hand, non-edited information. Also spent a few weekends with the GM of JP and we talked about it at length.

Yes, it is a better 22 caliber CF round than the .223Rem and it has an accuracy edge over the .22Nosler as well. For the vast majority of people, it won't matter. If you are shooting game animals out to 400 yards, varmints and rodents out to 600ish yards, paper out to 800ish yards as maximums, you might not see much benefit in the Valkyries. Realize that a driver of the development is the new "Gas Gun PRS series". If you want a bit more horsepower and range in an AR15 platform, yes, it makes a difference. At 1K, it carries the same energy as the 6.5Grendel and a trajectory very similar to the 6.5CM. Yes there have been arguments about bullets and chambers and twists, but 1:7 is fine for the 90s...but the 90 grain bullets, with the jumps, is the issue in my opinion.

On a squad at a Precision match with a .224 Valkyrie where it was shot (mostly against gas guns) from 87 to 1124 yards. I was on glass for many of those shots. We also had a .223Rem on the squad and the Valkyrie does things past 700ish that the .223Rem struggles with. IMHO, it is a niche round mostly for target shooting past 600ish. If you only plan to shoot out to maybe 600, probably not worth the effort. In a bolt gun, no way. Realize that 223Rem and 5.56 are not the same. If you get a proper chamber and twist, loading to 5.56 pressures, you can do quite a bit with the 5.56.

Yes, I built one, and I like it. But again, it won't replace my .223s for hunting and will likely only be shot in a few precision type matches here and there.
