Lee’s Safety Primer Feeder is for small and large primers, allowing you to never touch the primers from box to shell. It is used with 2006 and newer Breech Lock Challenger, Turret Presses, Classic Turret Press, Breech Lock Classic Cast, and the Classic Cast Press. Note: Depending on die configuration on the Turret Press, the Auto Disk Riser may need to be purchased to provide adequate clearance for the Lee Safety Prime.
