[QUOTE="MontanaRifleman, post: 339271, member: 11717"] Bigbuck, If you only partial FL size - just enough so the cases barely fit easily - you will reduce the the work stress on the brass. More importantly, if you use bushings for neck sizing, you will reduce the stress to the necks by a whole lot. I would recommend the the Redding type S FL bushing sizer, and set it to FL size the body and shoulder just enough to make the case barely fit comfortably, and set the bushing to partially size the neck, leaving a small un-sized area at the base of the neck where it joins the shoulder, which is what we call a donut. Bushing sizing is the most likely way to get your neck concentric and leaving a donut at the base of the neck is the best way to align your bullet (assuming that your bullet is seated concentrically) to the bore, assuming your neck chamber is concentrically aligned with youir bore which might be questionable in a factory tube. FL or partial FL sizing will actually help in getting your bullet lined up by giving the case a little play for the donut to align the case in the neck chamber. The absolute best way to go is custom bushing dies and Niel Jones is porabably the best maker of custonm dies, or at least right there at the top of the list. They will cost you though, just like anything that is made custom. Ohhh... I know a guy who use a standard Redding FL die with a floating expander ball in conjunction with a rubber "O" ring. He partial sizes, leaving a small donut and says his neck runout is less than .001. He uses a Redding Comp Seater also and shoots one hole groups with his 300 WSM. Mark [/QUOTE]
