I would agree with the above from my experience.
Been through the FL vs. neck sizing with the 280AI and have found the best for me is to just bump the shoulder back .001-.002 on every resizing. I found it is the best of both worlds and it sure improved consistancy in acccuracy.
The best purchase I ever made was a set of shell holders from Redding that allow you to do this with ease. I even bought a Innovative Tech. tool that allows me to measure shoulder bump and it verifies that the redding shell holder set is flat nuts on.
So - bottom line is I don't ever FL resize or neck size but I guess you would call it a partial FL resize every time.
