[QUOTE="Buffalobob, post: 405159, member: 8"] Do this then. Check what Rimfire has to say by taking out the seating plug and seeing if the tips are hitting or it is actually catching the shoulder of the bullet like it is supposed to. While you have it out, see if the plug is concentric inside. You should just be able to look and see if there is a problem Then take the plug and use your gauge to see if it is concentric outside with the threaded rod. Finally, and this is likely where the problem is, ( if not with the tips hitting), put everything back together and screw the die in and seat five bullets normally without any rotation during the seating process and mark each with an index so you know exactly how it was aligned in the die. Measure runout on each bullet and see if it is always the same in relationship with the index mark. If so, then it means your die is not in the press straight (or the seating cap) and you must unlock the lock ring and by trial and error reset the lock ring until it aligns the die vertically. If that does not help then do the same process with the seating cap rod to make sure it is vertical within the die. [/QUOTE]
