[QUOTE="ntsqd, post: 1645295, member: 93138"] Just discovered something interesting, the Bighorn Origin action is offered in "223, 308, Magnum or PPC/SPC (Valkyrie) bolt heads" [URL]https://bighornarms.com/product/origin-action-deposit/[/URL] I interpret that to mean that they sell you the same bolt for a PPC or a .30 Rem case based chambering. Since the PPC traces back to, essentially, the 7.62X39 case head size they're OK with exactly the fit that I'm pondering. [COLOR=#ff0000][B]EDIT:[/B][/COLOR] I see in their replacement bolt head section that they say to specify the caliber. So maybe I misinterpreted this. FWIW when I place a Valkyrie case in the Howa 7.62X39 bolt the extractor grabs it. If I slide the case as far away from the extractor as I can and then push on the neck sideways trying to lever the case out of the extractor's grip I can severely bugger the case rim, but I cannot pop it free.
