Hornady Powder Through Expander .400

The Hornady Powder Through Expander .400, item #290032, expands the case mouth during powder dispensing on a compatible progressive reloading press. Hornady designed this accessory for use with its Case Activated Powder Drop and the Lock-N-Load AP press. As a result, reloaders can combine case-mouth expansion and powder dispensing at one station.

Hornady Powder Through Expander .400 Features

• 10mm application: Suits cases for 10mm cartridges.
• Listed bullet diameter: .400–.401 inches.
• Combined operation: Expands the case mouth while the press dispenses powder through a compatible setup.
• Frees a press station: Removes the need for a separate case-mouth expander die on the Lock-N-Load AP.
• Bullet compatibility: Works with lead, plated and jacketed bullets when the selected components suit the cartridge.

In addition, combining these operations can leave an extra station available for another suitable component, such as a powder-check die or taper crimp die. Therefore, this expander can help make better use of the available stations on a progressive press.

Compatibility and Related Equipment

This expander works with the Hornady Case Activated Powder Drop system. However, it is not a complete powder measure or a standalone powder-dispensing unit. Before ordering, confirm that your press and powder-drop configuration support the expander.

Also, check the dimensions and requirements for your intended cartridge and bullet. The listed .400–.401-inch bullet diameter identifies the manufacturer’s application; it does not replace checking the correct components for your specific load.

For the complete press, see the Hornady Lock-N-Load AP Loader five-station progressive press. You can also view the Hornady L&L Powder Measure for related powder-measuring equipment.

For further compatibility details, consult the official Hornady Case Activated Powder Drop and Powder Accessories information.

Specifications

Finally, follow the manufacturer’s instructions when installing and adjusting the expander. Confirm that the components fit and operate correctly before reloading. Although combining expansion and powder dispensing saves a press station, it does not replace correct setup, powder-charge verification or safe reloading practices.
