[QUOTE="Pdvdh, post: 391698, member: 4191"] Do the neck bushings float free in your JLC converted dies, or with a 0.010" spitting gap surrounding the neck bushings? In other words, are the neck bushings positioned within the die snugly like the Redding neck bushing style dies? I have a .280 RCBS 30 degree shoulder and couldn't find any body die in that caliber, so I purchased and shipped off an RCBS FL sizing die for customization. I also shipped fired cases for customization to match my rifle chamber and when the die came back, the neck bushing rattled around loose within the die. I tried using it that way and was getting excessive runout as the neck bushing was floating freely and evidently shifting from the concentric position as the necks were sized down. So I'm wondering if that floating neck bushing design is the standard with the JLC modified dies? Anyhow, after getting the JLC modified RCBS die back and trying it out, I ended up purchasing a Redding S-style neck sizing die in .280 Ackley Improved with the 40 degree shoulder and using that for the neck and sidewall resizing. Then I use the JLC modified die in a second step without the neck bushings installed in order to bump the shoulders back. This two-step process yields pretty good results, but I had hoped the JLC modified RCBS die could be used as a one-step process. I also had to hone out the RCBS FL die because it was still oversizing the sidewalls of my casings excessively. So now the RCBS FL die is nothing more than a body die to bump the shoulder back after the Redding S-style die does the majority of the work. [/QUOTE]
