This will make the headspace length more consistent.

I would expect them all to be within about 0.003".
Randall, thanks - I do have two dies in the toolhead across from the trimmer. But I hadn't tried setting them down against the shellplate before setting the headspace. I was trying to do that afterwards.

0.003" would be great. I'll give it a try.
