That's actually funny cause full length sizing and bumping the shoulder back .002 is really just a cheap way of neck sizing folks been doing it a long time.the mandrel being dragged through is where inaccuracies are created hence the creation of lee collet die which keeps bullet concentric to bore
Alot of people say they are neck sizing while all along they are just barely sizing the case with a full length die.nothing new it's just knowing what your doing.
