RCBS Uniflow Powder Measure III Hopper with Cap

• Direct replacement fit: Built as a replacement hopper and cap for the RCBS Uniflow Powder Measure III, this set restores the measure to proper working order without adapting parts from other models.
• Threaded hopper design: The hopper matches the Uniflow Powder Measure III threaded system, making removal and reinstallation straightforward for cleaning, maintenance, or replacing a damaged hopper.
• Polymer construction: The polymer body keeps weight low and resists the everyday knocks that can happen on a busy reloading bench, while remaining practical for routine powder-measure use.
• Cap included: Supplied with the matching cap, the set helps keep the hopper covered during storage and between loading sessions, reducing contamination from dust and bench debris.
• Purpose-built spare part: As a dedicated powder measure accessory rather than a universal substitute, it is intended to return an existing measure to normal service with the correct form and function.

About the Uniflow Series

The RCBS Uniflow series is a long-running line of bench-mounted powder measures developed for reloaders who want repeatable charge dispensing for both rifle and pistol ammunition. In the RCBS lineup, Uniflow measures sit as core reloading tools rather than occasional-use accessories, making them a familiar choice for handloaders building consistent workflows around a press and scale. The series is known for its mechanical simplicity, bench-friendly operation, and emphasis on controlled powder flow.

Within the family, the Uniflow Powder Measure III represents the current evolution of the design, with tighter tolerances and a threaded anti-static hopper that simplifies disassembly and cleaning. That matters in practice because powder measures are handled often, cleaned periodically, and expected to maintain smooth operation over long loading sessions. The Uniflow concept is especially relevant to reloaders who switch between charge weights, load multiple cartridge types, or want a dedicated measure integrated into a stable bench setup. Across the series, the focus is not on electronics or automation, but on dependable manual metering, straightforward maintenance, and compatibility with the broader RCBS reloading ecosystem.

About the RCBS Uniflow Powder Measure III Hopper with Cap

The RCBS Uniflow Powder Measure III Hopper with Cap is a dedicated replacement part for the Uniflow Powder Measure III, intended for reloaders who need to restore a worn, damaged, or missing hopper assembly without replacing the complete powder measure. For a bench tool that handles powder every session, the hopper is more than a simple container: it affects day-to-day usability, cleanliness, and how easily the measure can be serviced. Replacing it with the correct RCBS part helps keep the measure operating as intended.

This model follows the threaded hopper format used on the Uniflow Powder Measure III. In practical terms, that makes removal easier when the measure needs to be cleaned or when powder should be emptied after a loading session. The polymer construction keeps the part light and suitable for routine bench use, while the included cap completes the assembly so the hopper can remain covered during storage or between loading runs. That is especially useful in reloading environments where dust, stray debris, or accidental contact on the bench can interfere with clean powder handling.

Because this is a purpose-built powder measure accessory, its value is in correct fit and straightforward restoration of function. It is suited to reloaders maintaining existing equipment, keeping spare parts on hand, or bringing an older Uniflow Powder Measure III back into regular service.

About RCBS

RCBS was founded in 1943 by Fred T. Huntington in Oroville, California. The company name came from Rock Chuck Bullet Swage, the original bullet-swaging die that started the brand. From those beginnings, RCBS developed into a specialist in ammunition handloading equipment for rifle and pistol cartridges.

Today, RCBS manufactures reloading tools in Oroville, California and focuses on products such as presses, dies, shell holders, powder measures, and priming tools. Its range covers single-stage, turret, and progressive presses, reflecting a broad approach to reloading, from basic bench setups to higher-output systems. In 2024, RCBS became a brand of Hodgdon Powder Company after its sale by Revelyst. For products such as powder measure accessories, that background matters because RCBS has long centered its design work on practical bench tools and replacement parts that support continued use of established reloading equipment.
