Reloading data for the 224 Valkyrie?

[lrrifleman]

I have recently become interested in building an upper in 224 Valkyrie for my thousand yard plus rifle, based upon the hype that this cartridge is receiving in the press. However, I want to do my homework. I have been having difficulty locating ANY reloading data for this cartridge. I would be interested in making loads with either the Sierra 90gr MatchKing or the Berger 90gr HPBT.

Has anyone seen any reloading data for this new cartridge? Thanks in advance for your assistance.

You got me. I'd never heard of this hot shot before you posted this. Did some digging with my friend, Google, and found this.:

30 years or so ago, I had a gunsmith friend who liked to play with wildcats. He would think one up and build it and I would help him figure out how to hand load for it. Today with the www and ballistic programs, etc, it just doesn't, seem to be as much fun as it was back then.
Good luck in your endeavor.
