The Hornady Bench Rest Metering Assembly (Model: 050114) is a fully mechanical reloading accessory engineered specifically for precision rifle cartridge preparation. Designed exclusively for use with the Hornady Lock-N-Load® Bench Rest Grade Powder Measure (Item #050130), this assembly delivers precise volumetric powder dispensing across a 20 to 65-grain charge range. Featuring a narrow, uniform metering chamber and plated internal surfaces, it works alongside an etched, indexed micrometer thimble to enable fine, repeatable powder charge adjustments without requiring electrical power.

Key Features

• Micrometer Adjustment Thimble: Features clear, etched index markings for repeatable adjustments, enabling handloaders to return precisely to recorded charge settings.
• Push-Button Quick-Change Design: Integrates directly with the Hornady Lock-N-Load push-button release system, allowing users to swap metering units without draining powder or disassembling the powder measure.
• Optimised Internal Geometry: Utilises plated internal surfaces and a narrow chamber profile engineered for uniform powder flow and charge consistency in intermediate rifle cartridges.
• Recipe-Specific Presetting: Allows reloaders to store individual, pre-adjusted metering units directly with specific reloading die sets for fast setup between calibres.
• Manual Operation: Fully mechanical design requires no electrical power or compliance certifications, operating entirely via manual control.

Who is the Hornady Bench Rest Metering Assembly for?

• Precision rifle handloaders — Charges intermediate rifle calibres (such as .223 Rem, 6.5 Creedmoor, and .308 Win) requiring a volumetric capacity strictly between 20 to 65 grains with micrometer repeatability using this bench rest powder measure insert.
• High-volume cartridge switchers — Provides a dedicated bench rest powder measure insert that can be preset to a specific 20 to 65 grains recipe and swapped via push-button release without draining the powder hopper.

Less suitable for: Handloaders dispensing small charges below 20 grains (which require a dedicated small-capacity pistol rotor or insert) or large magnum charges exceeding 65 grains (which require a standard powder measure fitted with standard or magnum rifle inserts).
