[QUOTE="MontanaRifleman, post: 906120, member: 11717"] Good questions Fred. The reamer neck is spec'd @ .3435 The necks are not turned. OD of a bullet seated neck is ~ .337 - .338 A bullet will snugly but easily slide in and out in a fires neck. The fired neck OD's are ~ .341 - .342 There should be more than enough clearance. In fact, if I had the chance to go back and spec the reamer again, I would tighten up the neck a couple of thou. The 6-284 neck is a little tighter and bullets fit slightly tighter into a fired neck than the RUM [/QUOTE]
