I’d go with a Big Horn TL3 action and either the 6 Arc or 6 Creedmoor with a Proof prefit for the Big Horn. I’d add a Manners stock, a trigger tech and it would be money. The thing about the 6 Creed is there’s ammo everywhere for it. Would be hard not to go with that chambering right now. I’m fact I’ve been having that internal battle lately. I want to build this exact rifle and would prefer the Arc but it’s hard not to go Creed just from an ammo availability standpoint.
