I'm neck sizing w/ a f/l die set. I have never neck sized before so it's new to me. When your finished neck sizing does it partially size down the neck or all the way down to the start of the shoulder. I backed my f/l die 1 turn and my cases come out looking like there is a buldge about 3/4 of the way up the neck. It just looks like it only sizes part of the neck. Is this normal? I have never seen what a case looks like after it was neck sized.
