Couple of reasons, one is that I thought that was taking the bell off it was .468 after sizing then .474 after expanding then back to 468. Second, that is right around were they started seating with correct headspace.
.468 or .469 seem I get this measurement across the crimp but I will assume a .001 tolerance is acceptable.
