[QUOTE="Mikecr, post: 737689, member: 1521"] Bart, your case centering because of an ejector plunger and re-headspacing on firing is a myth, because it's declared unqualified. A 6br or a 6xc doesn't do this, where a 243win might, because the shoulder angles are different. And there is the assumption of an ejector plunger, but standing blade, or no eject actions are common. This because some shooters do not want an ejector pushing cases out of centerline. My 6.5wssm action(BAT) utilizes standing blade ejection. The cases do not change in HS on primer firing. And they are held centered by correct sizing -with well under 1thou of TIR off ogives. This is a fitted chamber and the ONLY sizing needed, ever, is shoulder bumps(35deg, 1thou). With this, my bolt turns are smooth as cream. I have over 30 reloads on these cases, and their measured H20 capacity still matches logged at 3rd fireforming. I use a JLC body die for bumping, and I use a custom Wilson bushing die to slightly increase tension with -1/2thou & .125" length of sizing(cuz that's what my load liked). I also use only Wilson's for seating. I get the .125" length of sizing with a machine bushing, similar to a washer shim mentioned earlier. Now this is just one cartridge, an example for diversity in this discussion. I know that different cartridge designs result in different reloading plans, and that overall generalizations are usually wrong. All cartridge designs are not equal. Do 'FL bushing dies' size the entire neck? If so, I did not know this, and would concede that such a die would function as a FL die. I don't have any issues/dislikes at all with body-bushing dies. JLC Precision has made several for me. But I prefer separate body and bushing neck sizing myself. So I don't use JLC's dies with bushings. I leave that part to my Wilson inlines(removing the press). Where reloaders could get messed up is in talking about partial neck sizing with FL dies. Obvious to many of us is that partial neck sizing is different with a FL bushing die, than an actual FL die. This is why I don't like the TERM 'FL bushing die'. I call it a body-bushing die. Tryin to help here [/QUOTE]
