Buyer's Guide

Shelling out money for premium brass casings only to scrap them in the reloading process due to poor preparation can be frustrating. The Hornady Case Prep Duo streamlines your brass management by combining two essential tools - the Case Cleaner and the Case Length Tool - into an efficient workstation. This integrated system helps maintain consistent case dimensions and promotes optimal chamber fit for your reloading projects.

Case Cleaner Functionality

The Case Cleaner's dual action design agitates and cleans simultaneously, removing residue more thoroughly than traditional cleaning methods. Its versatile nature handles both aluminum and softer brass casings effectively, though more delicate cases might require gentler handling. The tool's quick-connect system allows for easy changing between cleaning solutions and enhances overall efficiency at the reloading bench.

Selecting the Right Components

When choosing between aluminum and steel components, consider frequent vs. infrequent use. Aluminum offers lighter weight and reduced cost, making it suitable for occasional reloaders. Steel components provide longer-lasting durability and are better suited for high-volume reloaders who process brass daily. The Case Prep Duo's standard configuration includes a stainless steel tool and aluminum cleaner, combining reliability with weight savings.

Tool Maintenance and Storage

Regular cleaning and maintenance extend both the Case Prep Duo's lifespan and its performance. After each use, thoroughly rinse the tool to prevent residue buildup and potential clogging. The steel tool requires periodic lubrication of moving parts, while the aluminum cleaner should be stored in a dry environment to prevent corrosion. Proper maintenance increases tool longevity and ensures consistent case preparation results over time.

Brass Case Considerations

Not all brass casings respond equally well to the Case Prep Duo's processing. Extremely thin-walled or damaged cases may become distorted during cleaning or sizing, potentially rendering them unsuitable for reloading. Before committing fully to the system, test process several representative casings to evaluate how they retain their original dimensions and shape after preparation. This trial period helps determine if the tool meets your specific brass case requirements.

FAQ

What is the Hornady Case Prep Duo?

The Hornady Case Prep Duo is a two-station cartridge sizing press system designed to manage headspace and maintain proper case dimensions during reloading. It includes two interchangeable sizing heads, one for small cases and one for large cases.

Hornady developed this press to address common issues in reloading, particularly with headspace variances and case neck stretching, which can affect both accuracy and safety.

What are the key features of the Case Prep Duo?

The Case Prep Duo system features precision-machined sizing heads that allow for adjustments in 0.001-inch increments. These heads accommodate cases ranging from 0.100 to 0.380 inches in diameter, making them suitable for a wide variety of cartridges.

The system includes a precision crimping die that works with standard crimping collars to maintain proper bullet placement. It also features a built-in tool storage system and quick-change head mechanism for easy switching between small and large case sizes.

How does it improve headspace accuracy?

Through its precise 0.001-inch adjustment capabilities and interchangeable sizing heads, the Case Prep Duo allows shooters to maintain consistent case lengths across multiple reloads. This is crucial for achieving proper headspace measurements, which directly impact cartridge reliability and firearm functionality.

The system's ability to manage case neck stretching is also enhanced through its controlled pressure application and consistent sizing process, ensuring that each case maintains its original dimensions while being seated properly in the chamber.

What size cases can it handle?

The press requires a power source (typically air or electric), standard reloading dies, and brass cases to operate. The included crimping die works with standard crimping collars, ensuring that users can complete their reloading process without additional equipment purchases.

What's the learning curve for using the Case Prep Duo?

While the Case Prep Duo offers significant precision improvements, it operates using standard reloading techniques. Users familiar with basic reloading procedures will find the system intuitive, though some practice may be needed to master the 0.001-inch adjustments.

Hornady provides comprehensive instructions with the system and offers detailed guidance in their reloading manuals. The precision features may require users to adjust their workflow, particularly in measuring and inspecting case dimensions after sizing.
