Neck-sized rounds. The idea is for all of the rounds in a set to have exactly the same resistance (via the turning of the bolt). Any hard turning of the bolt (particularly of individual rounds) is not helpful to accuracy because it upsets the hold or placement of the rifle (and is very distracting). My neck sized rounds do not have noticeable resistance when turning down the bolt. If the rounds begin to have resistance, I full-length size the cases and test them in the rifle to be sure they do not have resistance, checking that the cases are not being sized more than necessary (which leads to case-head separation, which is also distracting).
