[QUOTE="DJ Fergus, post: 1934434, member: 93895"] I see what you're saying. It makes good sense. Right now, the donut has an opening that's greater than .261 but smaller than .263, so say it's .262. I've got Lee making a Collet die and the mandrel should end up @ .261. Assuming .001" spring back, the Collet die should leave the sized neck at about .262" The donut may not be quite as much of an issue as I thought but I will see. If that doesn't work, I will take your advice and pre expand with a .263 or larger mandrel & partial neck size above the donut area if need be. If the donut it still there, I think I will be able to feel it in seating the bullet. [/QUOTE]
