[QUOTE="MontanaRifleman, post: 310301, member: 11717"] Hmmmm... I have turned previously fire case necks without any problem, but with my 7mm, I only partially turned them. With my 300 RUM I turned them all the way to the shoulder. They were fully neck sized using an expander ball. Tlk I have never used a Lee collet style sizer, but I think if the neck were sized correctly (slightly smaller than the bullet diameter) and you used the correct size pilot reamer, there should not be any slop, even with previously fired brass. Something is not right. Also, just because you cant seat the bullet manually, doesn't mean the neck is sized properly. You should mic the inside diameter. Hope you get it figured out. -MR Also, my technique is not to trim until they have been fired. I do agree with turning unfired brass if you can, but if you get once fired brass, I dont see anything wrong with turning it if you fully size the necks with an expander ball. [/QUOTE]
