The Hornady Hand Held Priming Tool (Model 0500021) is a manual mechanical priming device designed for off-press seating of small and large primers into metallic cartridge cases. Operating via a full-hand squeeze lever, it delivers the mechanical leverage and direct tactile feedback required to feel Boxer-type primers bottom out consistently in primer pockets. The tool eliminates the need for bench-mounted press operation during the priming stage, enabling portable batch processing.

Key Features:

• Full-Hand Squeeze Mechanism: Utilises a pliers-style hand lever to drive seating punches, reducing hand fatigue compared to thumb-actuated priming systems.
• Dual Shell Holder Compatibility: Includes two dedicated primer trays—a black tray engineered for standard Hornady shell holders and a green tray configured for standard RCBS shell holders.
• Captured Internal Components: Features integrated tray bushings that retain the seating punch and return spring inside the assembly, allowing shell holder swaps and size conversions without loose small parts dropping out.
• Integral Primer Orientation: Features a tray cover with molded directional ribs designed to flip inverted primers upright with gentle shaking.
• Complete Primer Size Coverage: Ships with interchangeable punches and bushings to accommodate both Small Rifle/Pistol and Large Rifle/Pistol Boxer primers.

• Primer Capacity: Accepts standard 100-primer packaging trays
• Primer Compatibility: Small Rifle, Small Pistol, Large Rifle, and Large Pistol Boxer primers
• Shell Holder Fitment: Standard-profile Hornady and RCBS press shell holders (sold separately)
• Packaged Weight: Approximately 1.215 lbs (~551 g)

Who is the Hornady Hand Held Priming Tool for?

• Precision rifle handloaders — provides direct mechanical leverage to manually feel primer cups seat uniformly against the bottom of primer pockets across both Small Rifle/Pistol and Large Rifle/Pistol primer configurations using standard Hornady and RCBS shell holders.
• Batch-priming reloaders — allows off-bench priming of metallic cartridges away from a fixed press by holding up to a full 100-primer tray in its self-contained, orientation-ribbed reservoir.

Less suitable for: High-volume, continuous reloading workflows requiring hundreds of seated rounds per hour, or non-standard primer types such as shotgun 209 or .50 BMG primers (which exceed this tool's small and large Boxer primer operating envelope); progressive reloading presses and dedicated bench-mounted priming systems are better suited for bulk production.
