Re: 338/300 RUM reamer recomendation
i hate to do this, but i'm going to respectfully disagree with Shawn. of course he has about 100 times more experience with this than i do, but i'll tell you about my "one" example. when i was ordering a reamer for this cartridge, i wanted a no turn neck, and i was told that loaded rounds with the edge, without turning the necks, would be about 365. i ordered a 368 neck and when i measured my Rem brass with a 300SMK in it, it was 368, and yes it was pinching when attempting to chamber. wasn't a big deal, i just take the high spots off so my loaded rounds are 365 and it works well. my point is i consider 369 a little "too tight" for a no turn neck with an edge. again this is my "one" experience but it's been the same with 2 different lots of Rem brass.
