Wally, I ordered the 28"+2for the Vias brake, 9 twist(ratchet). It should like the 300 OTM's.
I hear stories about good and bad barrels from every manufacture. My friend bought a S&W 44Mag, new, barrel was galled 1" inside, riflings and crown F'ed up(
.13" off center at muzzle). would never be a shooter. My original Savage mod 12 bull in 204Ruger shot every bit as good as its Shilen replacement. But like Jon said, his Bartlein shot better than his shilen. Lija put up a bore scope video showing a new 300WM Rem 700, it was horrible! Tooling has a lot to do with how nice the barrel turns out. From boring to pulling the button to cutting the chamber and crown. New tooling will almost always put out the best barrel.
All manufactures put out good and bad barrels. If you can, go for a hand lapped match or select match and check for trueness of the chamber when you get it. Tell them it will be for ELR out to 1 mile. If its a good company, they will hand pick you a good barrel.
