The Hornady Primer Pocket Cleaner - Large is a manual reloading hand tool engineered to remove baked-on carbon residue and spent primer fouling from large cartridge cases. Designed for cartridges utilizing Large Rifle (LR) or Large Pistol (LP) primers, this tool features precision-ground flat scraper blades that clear the bottom and internal corners of the primer pocket. Thorough carbon removal allows fresh primers to seat consistently below flush, mitigating the risk of misfires and high-primer slam-fires. Built with an unpowered mechanical design, the unit weighs approximately 0.095 to 0.10 lbs (~43 to 45 g) and includes a knurled universal accessory handle for non-slip manual operation.

Key Features

• Precision Scraper Head: Flat-ground blades clean fouling and carbon buildup from the pocket floor and internal edges.
• Modular 8-32 Thread: The scraper head unthreads from the handle via standard 8-32 threading, allowing direct installation onto motorized case prep centers or multi-tool power stations.
• Ergonomic Hand Tool: Equipped with a knurled aluminum handle designed for controlled, slip-resistant manual twisting at the reloading bench.
• Mechanical Operation: Functions entirely by hand without requiring batteries, external electricity, or mains power connections.

Who is the Hornady Primer Pocket Cleaner - Large for?

• Hobbyist reloaders processing small-to-moderate batches: Processes routine brass runs of 20 to 100 cases using an ultra-lightweight 0.095–0.10 lbs (~43–45 g) manual hand tool that operates without bench power or complex setup.
• Precision rifle reloaders: Cleans large primer pockets measuring ~0.210" (~5.33 mm) in diameter—such as .308 Winchester and .30-06 Springfield—ensuring uniform primer seating depths across fire-formed brass.

Less suitable for: Cartridge cases with small primer pockets measuring ~0.175" (~4.45 mm) diameter, which require a dedicated small primer pocket cleaner; processing bulk brass quantities exceeding 100 cases per session, where a powered case prep station reduces manual hand fatigue; or military brass requiring crimp removal, which necessitates a dedicated primer pocket swager or reamer rather than a scraper.
