I like this about full length sizing:
But the trick is sizing the case just enough to allow proper feeding/extraction and no more.
From what I've seen and learned over the years, how much is "just enough" varies between those shooting bullets the most accurate. Some folks so a lot, others very little, in how much fired case diameters and shoulder setback is used. The most consistant between them is the case shoulder. The limit seems to be 2 thousandths for 30 caliber and smaller. Some folks reloading for 33 caliber super magnums go 3 to 4 thousandths and the 50 caliber BMG crowd as much as 6 to 8 thousandths.
