The Hornady Lock-N-Load AP Progressive Press Large Primer Tube (MPN: 398358) is a factory-original metal feed and pick-up tube engineered specifically for the Hornady Lock-N-Load Auto-Progressive (AP) reloading system. Measuring approximately 14 inches (35.5 cm) in total length, this mechanical accessory allows reloaders to collect large primers directly from a flip tray via a flexible polymer tip. By facilitating hands-free collection, it protects primers from oil and moisture contamination while holding up to a full tray of approximately 100 primers to maintain continuous, high-volume production on progressive and compatible Iron Press setups.

Key Features

• Factory Progressive Sizing: Engineered at an extended 14-inch length to hold up to 100 large primers, matching the operational capacity requirements of progressive cartridge assembly runs.
• Contamination-Free Pick-Up: Features a flexible polymer tip designed to capture primers directly from a primer flip tray, eliminating direct finger contact and potential contamination from skin oils.
• Durable Construction: Built with a rigid metal body weighing between 0.17 and 0.19 lbs (77 to 86 g) for consistent, smooth gravity feeding into the press primer housing.
• Batch-Loading Efficiency: Enables progressive reloaders to pre-fill multiple tubes before starting a reloading session, minimising machine downtime during high-volume assembly.

Who is the Hornady Lock-N-Load AP Large Primer Tube for?

• Hornady Lock-N-Load AP progressive press operators — Requires an exact OEM-fit progressive reloading primer tube measuring 14 inches in length to integrate directly with the Lock-N-Load AP priming housing and maintain a full 100-primer feed cycle.
• High-volume rifle and pistol reloaders using large primers — Needs to stage multiple 0.17 to 0.19 lb metal tubes pre-loaded with approximately 0.210-inch diameter large primers to run continuous cartridge assembly without interrupting press operation.

Less suitable for: Reloaders assembling small-primer calibres such as 9mm, .223 Remington, or .38 Special, who require a dedicated small primer tube, or users of the 1911 Auto Primer Tube Filler system operating without dedicated machine adapters.
