RE: OK to neck size with full-length dies?
Partial full length resizing is what is done with a full length sizing die backed off of the shellholder a bit. The best way to do this is to use a set of stoney point gauges and measure the amount of shoulder setback on your brass. When you've adjusted the die to give .001-002" setback then you've got it adjusted properly. Barring that, keyshunter's method works well. Partial full length sizing will extend the life of your brass, especially if you're using belted magnums. I much prefer the partial full length sizing method to neck sizing when making hunting ammo. I want the stuff to chamber easily and a partial full length sized round will chamber easier than a neck sized one.
