In general, there is very little room for a bullet to slide between the rising shell plate and the underside of the bullet seating die. Handgun bullet seating dies are designed with a taper at the bottom of the die and are adjusted three turns off shell plate contact. The taper at the base of the die mirrors the shape of the bullet feeder fingers and spreads them as the case mouth meets the bullet base. All this is designed to work in a space of .46" to .80" depending on caliber.nimblebee wrote:One thing puzzles me is why Lee's bullet feeder doesn't work with rifle
bullets? The tinkerer in me is drooling over this issue.
Rifle bullet seating dies work a bit different and are made to meet the shell plate; hence; they have a flat base.
