Lyman has introduced a dramatic improvement in hand-held priming systems: The E-ZEE Prime Hand Priming Tool. The system works with any popular brand of shellholder and allows instant changeover between primer sizes. Lyman's E-ZEE Prime Tool includes two primer trays, each of which incorporate their own built-in large or small primer punch assembly. There are no small parts to fuss with or lose. Each tray has a built-in shut-off gate to keep primers in place during change-over. The reloader simply removes the snap-in-place lock collar and installs the correct sized primer tray and his standard shellholder as needed. Then the lock collar is snapped in place and the change-over is complete. The primer trays also function as a primer flipper to properly orient primers for seating. In addition, the tool has a comfortable ergonomic design that works with the tool's optimized leverage system to reduce hand fatigue. Features: Ergonomic shape designed to minimize hand fatigue Accepts all popular brands of standard shell holders, including Hornady, RCBS, Redding, and Lee Precision Plenty of leverage, yet provides needed "feel" for precision primer seating Integral primer tray and primer punch assembly - no small parts to lose Comes with large and small size primer tray/primer punch assemblies Primer tray has a built-in shut-off gate to prevent spilling primers Primer tray doubles as a flipper to orient primers for use
