I see Rainier has these on sale and I'm wondering if anyone has tried one? I have a build just in need of a barrel. I have seen good results with their .223 barrels but their 1-7.5 twist scares me for the Valkyrie. Berger's twist rate calculator has it only marginally stable for even the 80s.
Rainier claims that works but I don't know what altitude they're at. I'm at sea level.
