[QUOTE="Forester, post: 218872, member: 11102"] OK, heres an overdue update...I do use a VLD chamfering tool so that was not the issue. I went back and started at the beginning with some recently fired Lapua cases. With these I checked runout after every step in the process and found they had very little to none after they were fully prepped. When I seated a bullet in these cases I was back to my old, good, low runout numbers. The only thing I changed was that the press and all dies involved got an extremely thorough cleanup. I did find some buildup under the universal shellholder base plate which could have forced the case to sit off square with the rest of the press. I thought I had these things covered before but apparently this was more a case of "garbage in, garbage out" than any big mystery. I sure wish I had had the good sense to check the easy things first before I got into all the checking, measuring, and general hair pulling I went through. Thanks to those who had some input on this. If something good came from it, at least I have been through my loading process pretty throughly now and looked at everything pretty closely for problems or potential problems. [/QUOTE]
