The Lee New Auto Prime Hand Priming Tool is the updated version of a time tested classic. The Auto Prime has been designed to work with every brand of primer and features the patent pending "elevator pin" which safely separates a single primer from the tray reducing the likelihood of tray detonation. The Auto Prime uses the same body and shell holders as the original but the rest of the components have been improved or replaced. Some of the upgrades include an unbreakable comfort curve lever and large triangular trays that accept all brands of primer boxes with slide on covers for large or small primers.
