New brass and the 90 atips I think was the problem. I switched to 85.5s and 88s in new brass, and the majority of the issue went away. Maybe the alpha 22gt had runout prior to seating but the ones I checked were straight.
SAC "The seating die" horrible runout

OK, I wasn't sure if you had sent in the seater to get modified/switched-out or if you used a different bullet profile like the tech support mentioned.
I have found 0.005+ and sometimes MUCH more runout with virgin brass that then shows 0.0005-0.001 TIR after seating bullets in fired brass so that would make a lot of sense.
That's using your Wilson inline dies? I could see them straightening things out upon seating if so.
That's with SAC and Wilson I get those results with fired in my chamber brass that has then been bumped back 0.0015-0.002, neck squeezed down 0.004 under loaded diameter then opened back up 0.002 with my 21st Century mandrel...
The biggest difference i see with the LE Wislon vs the others is the dead nuts consistency of seating depth round after round and the exact 0.001 seating depth adjustment from one line to the next.
Interesting thread. I guess my only contribution to it would be my personal observation that "multi-caliber" reloading stuff (like this multi-size seating die) will pretty much "never" be better than components designed for one purpose and one size. Pressing the "Easy Button" for stuff like this has never worked for me. But that's just me ...
Very similar to what I do, with great consistency. Anneal (AMP), shrink (bushing die), expand (mandrel), charge and seat. Only addition to that is my advice to you all to take a hard look at the AMP Press ... it's awesome ... not cheap ... but awesome nonetheless.
