I tried the o-rings... It really did help.

I have an RCBS seating die that's always been a problem child. I normally load .45 on a Dillon with a Dillon die (no problems whatsoever), but I loaded about 50 yesterday to help clear some crap off my bench, squared up the die on the single stage with some pennies, and had the O-ring under the lock ring. They loaded really straight, no shaving lead and no obvious bulging on one side vs the other. I was pretty happy. I'm betting it will help with leading as well.
I can't measure concentricity on a .45... the cartridge is too short. I did try the o-ring trick on some .223's the other day. The most runout I had on any of those was .0015" with most being well under .001".
