Hornady Primer Pocket Reamer for Lock-N-Load Case Prep Trio - Large

The Hornady Primer Pocket Reamer for Lock-N-Load Case Prep Trio (Large) is a precision reloading accessory designed to deburr and clean primer pockets in large rifle and pistol cases. Compatible with Hornady's Lock-N-Load Case Prep Trio and Power Case Prep Center systems, this reamer attaches via 8-32 thread interface, allowing shooters to standardize primer pocket dimensions for consistent seating depth and ignition reliability across handloaded ammunition batches.

Proper primer pocket prep is a critical but often overlooked step in the handloading process. Flash holes can develop burrs during case forming and firing, creating uneven primer seating that affects ignition consistency. The Hornady reamer removes these burrs and chamfers the pocket edge, ensuring uniform primer pocket depth across your case lot. This level of attention translates directly to tighter velocity spreads, improved accuracy potential, and reduced pressure variations—especially important for precision rifle loads and match ammunition. The small 0.02 lb tool integrates seamlessly into your bench setup without cluttering workspace.

Reloaders serious about ammunition consistency—whether for long-range hunting, competitive shooting, or precision rifle competition—recognize that case prep quality directly impacts shot-to-shot performance. The large reamer is sized for full-power rifle cases and large magnum pistol cases. When paired with other Hornady case prep accessories like pocket cleaners and neck brushes, this tool completes a comprehensive prep station that handles everything from deburring to brushing in a single workflow.

The 8-32 thread standard ensures compatibility with the entire Hornady Lock-N-Load accessory ecosystem, allowing you to swap tools without breaking down your press. This modular approach lets handloaders build a customized prep center matched to their specific caliber requirements and production volume.
