[QUOTE="Katbird, post: 292694, member: 14358"] There are no dumb questions. They keep us from actually doing dumb things. You can't neck size with a full length sizing die without also partially resizing the case, but you can size the case less by backing out the die until only about 3/4 of the neck is sized. Screw your full length sizing die into the press and back it off one and a half turns. Mark a case with a magic marker from the case mouth down past the shoulder and run the case into the die. Look at the case. More than likely, you will see that the shoulder has also been in contact with the die, squeezing the case down a little smaller at the shoulder. This pushes the excess brass up the case where the datum line of the case contacts the corresponding datum line on the chamber. This is where you need to be setting your shoulder back about .0015" to ensure easy chambering. Play around with your die until you only size about 3/4 of the neck. If you can leave a small portion of the neck unsized, the unsized portion of the case centers in the chamber. You also size the case less than you would if you set up your die to size the entire neck. If this works, you are in great shape. Your best bet is to use a body die and a Lee collet neck sizer.
