Gentlemen, I am looking to build a 358 WSM. I am planning to use a Winchester M70, classic stainless that is now a 270 WSM and rebarrel it with a Pac-Nor #4, 1-12 twist. Does anybody know where I can find a reamer? I figure this has been around for a long time so somebody has to have one.... but, I don't know what to ask for. Is it technically called a 358 WSM or 35 WSM or 350-300 WSM or what.
Any info that you guys could give is greatly appreciated.
Thanks in advance,
Bob
