The E-Zee Prime Hand Priming Tool from Lyman is designed with an ergonomic shape to optimize leverage and minimize hand fatigue. The system works with any popular brand of standard shellholder and allows instant change-over between primer sizes. Includes two primer trays, each of which incorporate their own built-in large or small primer punch assembly-meaning 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 size primer tray and the 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. Weight: 2 lbs.
