Redding Model 3 Universal Metering Chamber

• Broad charge range: The universal chamber is set up for approximately 5 to 100 grains, making it suitable for a wide span of rifle loads without changing to a different metering setup for every recipe.
• Fits Model 3BR measures: Built specifically for Redding 3BR powder measures, it gives reloaders a direct replacement or spare chamber that keeps the measure working with the same intended geometry and adjustment feel.
• Micrometer-style adjustment support: Used with the Model 3 system, the chamber allows repeatable setting changes, which helps when returning to known powder charges during load development or batch production.
• Steel construction: A steel body suits bench use where repeated installation, adjustment, and handling demand durability over long reloading sessions.
• Useful spare for workflow efficiency: Keeping an extra metering chamber ready can reduce setup time between loads, especially for handloaders who record settings and want faster changeovers.

About the Model 3 Series

The Redding Model 3 series is the company’s long-running family of powder measures for handloaders who want dependable volumetric dispensing and repeatable adjustment. In Redding’s lineup, the series covers both the Classic Model 3 and the Model 3BR, giving reloaders a proven platform for general rifle loading as well as more precision-oriented bench use. The design centers on a front-mounted micrometer-style metering system that is easy to read, easy to record, and practical for returning to established charge settings.

Across the series, the emphasis is on mechanical consistency, broad charge capability, and durable bench construction rather than unnecessary complexity. Model 3 measures are intended for reloaders working with a wide range of smokeless rifle powders, from routine ammunition assembly to more careful load development. Interchangeable metering chambers are part of that flexibility, allowing the same basic measure to be adapted to different charge ranges and applications. For shooters who value repeatability at the loading bench, the Model 3 family remains a practical choice because it combines a straightforward operating layout with the kind of adjustment system that supports organized, methodical reloading.

About the Redding Model 3 Universal Metering Chamber

The Redding Model 3 Universal Metering Chamber is a dedicated accessory for the Model 3BR powder measure, intended to cover the broad charge range most often associated with rifle handloading. Its approximate working range of 5 to 100 grains makes it useful for reloaders who want one chamber that can handle many common powder charges without switching to a more specialized insert. In practice, that means less interruption when moving between different rifle cartridges or refining several loads in the same session.

Because this is a separate metering chamber rather than a complete powder measure, its value lies in convenience and repeatability. A second chamber can be kept set for a known load, reducing the need to dial back and forth between recipes and helping preserve established settings in a more organized workflow. That is especially helpful for handloaders who keep detailed records and want faster setup when returning to a proven combination.

The chamber’s steel construction suits repeated bench use, installation, and adjustment. Its black finish keeps the appearance consistent with the rest of the measure assembly, while the dedicated fit for the 3BR platform helps maintain the intended operating feel of the system. For reloaders using a Redding broad-range powder measure, this accessory is a straightforward way to expand flexibility while keeping the familiar Model 3 adjustment concept in place.

About Redding

Redding Reloading Equipment was founded by Burr Bement in 1946 in Virgil, New York. The company focuses on tools and equipment for handloading ammunition, with a product range that includes reloading dies, presses, powder measures, scales, and case-preparation tools. That long specialization has made Redding a familiar name among reloaders who value precise mechanical tools for rifle and handgun ammunition assembly.

Over time, the company expanded both its identity and product offering. It was incorporated as Redding-Hunter, Inc. in 1956, and in the 1960s it began marketing products under the Redding Reloading Equipment name. Redding is also known for product lines such as Type S bushing dies and Competition series dies, which reflect the company’s strong emphasis on repeatable adjustment and careful cartridge preparation.
