For concentricity, I've found these Wilson seaters excellent. Always within 1/1000th. With K& M arbor press

What steps are you using to resize your brass? @garandman
get the arbor press with force gauge. i sort my reload by pressure when seating the bullet. the reload batch stay within 5 ES
I wondered about that / neck tension, and how to account for it. I do get some notably different resistance in seating the boolit.
The arbor press is much smaller and lighter unit, you will feel the slight different of resistance. If the press equipped with the force gauge, it measures how much force need you to seat the bullet. At the end, it is a great tool for me. My process are resize the brass with body die with traditional press then neck size and bullet seating with arbor press. It gives me great result of single digit ES. Can you achieve the same with traditional press? I believe it can, but much harder for me.
What neck sizing die you using with the arbor press?
I suspect neck ension is the next "evolution" in my reloading development.
Cheapest way to get the most consistent bullet tension is with a Lee collet die. to do it with a bushing die usually requires neck turning.I wondered about that / neck tension, and how to account for it. I do get some notably different resistance in seating the boolit.
