Re: 338 Win mag barrel, What length and....
I went with a 27" for my 338WM.
The 1-12 shoots great with the 200-225 gr bullets but, if there's any chance you'll shoot anything heavier go with a 1-10.
Contact Steve Satern at 712-362-4991. Short wait time and excellent customer support.
I'm currently shooting his barrels on a 300 and 338 Win Mags, 338/375 Ruger and 338 Lapua.
Overall very impressed, on par with the best out there.
