Hornady 9991 One Shot Case Lube 5 oz Aerosol Spray

The Hornady One Shot Case Lube 5 oz aerosol spray is a dry-film case lubricant designed to streamline the reloading workflow for handloaders processing volume. Unlike traditional paste lubes that require messy application and cleanup, One Shot applies evenly across entire blocks of cases in seconds and dries within minutes, letting you move through prep work faster without the sticky residue. It's engineered as a non-petroleum formula that won't contaminate powder or primers—a critical safety advantage when you're managing multiple cartridges on the bench.

Reloaders choose One Shot for its clean, no-fuss application when loading large quantities. The dry-film technology distributes uniformly over case surfaces without creeping or migrating, which means consistent lube coverage every time. Because it doesn't leave behind oily residue, you spend less time cleaning cases and more time at the press. The lubricant is formulated to reduce drag during case extraction and help prevent scoring or scratching of brass, protecting the longevity of your casings across multiple reloading cycles.

Beyond cases, One Shot works as a general-purpose lube for reloading equipment. A light coat on your press, dies, and other tools improves performance and extends service life by reducing friction and wear. The spray format makes targeted application easy—hit the contact points without over-lubricating. For semi-automatic shooters, the reduced buildup also helps minimize jamming issues that can occur when excess lube accumulates on cartridges.
