Introduced in 1979, the original Lee Auto Prime was limited by its ability to accept only certain brands of primers. This updated version does not have that limitation and will function well with any primer brand. A patent-pending elevator pin safely separates a single primer from the others and presents it for priming, greatly reducing any possibility of a chain fire. A new, unbreakable comfort curve lever makes the priming process more comfortable and reduces hand fatigue. Includes two primer trays that accept all brands of large and small primers in a size and shape that makes transfer of primers from the manufacturers box to the tray easy with less chance of spillage. NOTE: Shell holders are not included with this priming tool. The manufacturer offers special shell holders for use with this tool. Standard shell holders will not fit this tool.
