[QUOTE="Buffalobob, post: 365649, member: 8"] Measure it at the same place on the neck both times. If your neck is out 0.003 then simple geometry says your bullet when seated will be out more than 0.003. Couple of standard, cheap, no money spent, fixes to try. They may not work but they are free. 1. Take the retaining pin out that keeps the shell holder in place and let the shell holder float. You can put a rubber band or O-ring there is you wish. 2. Take your die in your hand and observe the simple fact that threads on the body are spiraling around at an angle. Grab the lock ring and observe the fact that here is slop and play in it so that it will spin freely around on the die body threads. Reach up and turn the switch to your brain to the "ON"' position. Think for a minute and conclude that it is possible to lock the lock ring in a position that causes the die body to not be straight up vertical. Grab three or four cases and your runout gauge and screw out the expander ball and lay it aside. Start running cases up into the die body and loosing and re-tightening the lock ring to see if you can get the die body to be vertical. Once you are getting straight necks out of the die body then put the expander ball back in and tighten it and run the cases in and see if that problem is cured. If it is not cured then try a sloppy loose expander ball and see if it will pull out straight when it is free to self center. Lube the inside of the neck to reduce binding. May not fix your problems but it will get you some practice setting up your press and dies properly. [/QUOTE]
