my most accurate rifle is a Pac Nor Barrel reject.. before he got big and famous, he was just a local guy trying to get into gunsmithing.. he'd worked for PacNor over in Brookings..
but John Noveske, sold me a 6mm Stainless Barrel, threaded it and chambered it in 6mm Rem on a Rem 700 LA, recommended an 11 degree crown....1 in 7 twist... all for $75!
He was up front that it was a Pac Nor Reject....
Got multiple barrels on rifles, that were Pac Nor "Rejects", that I got from Noveske and him doing the work on them, each are among the most accurate rifles I have.
