It's funny how rarely in the forums anyone mentions Berger bullets as their choice--any particular reason?
My advice--get more than one box--maybe three or four--if you really want to find the "Eureka" load. : ) I think John hit the nail on the head about the bullet seating position and concentricity to the chamber/freebore--which means even after finding a good charge weight lots of experimentation with seating depth in my experience.odd that you made this thread Stag. Earlier today I was contemplating buying a box of Bergers to try in the new build after reading this article
https://precisionrifleblog.com/2019/...6br-load-data/
seems like the the vanilla 6BR 105 Bergers and 108 ELDM's are the schnitzel. I might come off my wallet and buy a box tonight

I was an early adaptor of the valk--built three of them in various length/twist combinations; the valk is a perfect example of having to get it "just right" in the chamber, twist, seated depth and velocity. The 90 is heavy (though I came up with a great load for the 95 gr matchking) and in my experience needs fast twist and fast velocity to stabilize well. Hornady's 88 eld was the first 224 bullet that really addressed optimizing the design of the larger bullets used for the valk. Adding to the problem was a lack of consistency in applying "true" SAAMI standards for the chamber reamers used by the various manufacturers upon the roll-out of valk barrels. Federal's roll-out was less than graceful and came close to killing the valk IMO. Also it's better to switch to the small primer cases IMO.I don't know if it's the weight or the manufacturer, but it's well-known and I can confirm, that a 90 grain Berger VLD in 224 Valkyrie shoots less well than a Hornady 88 grain...at least to the best of my ability (and others, by reports).

What's "center of pressure?"I think because of their complex ogives, center of pressure etc they are a little more demanding of fine-tuning than most other designs--but that's just a theory.
