Texas10 is right on the money with neck tension variation. Using a screw in die some times a tight neck will not fully seat a bullet with a consistent stroke of the press. If you want the consistent seating depth, try using an expander mandrel (like a a k&m) not the one in your sizing die along with an arbor press and a Wilson seater. You will see a noticeable difference.

I’m FL sizing with honed neck from Forster (without the expander button) then expanding with a Sinclair mandrel .002” smaller than bullet diameter...
