The Redding Model 3 Powder Measure with Handgun/Pistol Metering Chamber (03100) is a dedicated bench-mounted tool designed for precise, low-volume smokeless powder dispensing. Built with a precision-machined, hand-honed cast iron frame and a hard chromium-plated rotating drum, it delivers clean shearing across small extruded, flake, and ball powders without binding. Featuring an integrated front-facing micrometer metering chamber, it provides direct visual reference and fine adjustments for light powder charges ranging from 0 to 10 grains.

Key Features

• Handgun Metering Chamber: Includes a front-facing micrometer metering chamber calibrated for fine adjustments between 0 to 10 grains of smokeless propellant.
• Cast Iron & Chromium Construction: Features a hand-honed cast iron body and a hard chromium-plated drum that cleanly shears powder grains to ensure consistent volumetric throws.
• Standard Thread Mounting: Integrates standard 7/8"-14 reloading threads to fit standard reloading presses, bench stands, and the included mounting bracket.
• Wide Calibre Drop Tube: Equipped with a clear drop tube configured to guide powder into case mouths ranging from .22 to .50 calibre.
• 100% Mechanical Operation: Operates manually via lever action without the need for mains power or batteries.

Who is the Redding Model 3 Powder Measure With Pistol Chamber 03100 for?

• Handgun cartridge reloaders — dispenses light smokeless powder charges within a dedicated 0 to 10 grains window, providing the fine adjustment required for pistol cartridges such as 9mm Luger, .38 Special, and .45 ACP using this handgun reloading powder measure.
• Small-capacity rifle and target handloaders — provides precise volumetric dispensing directly into case mouths sized from .22 to .50 calibre via the included clear drop tube on this handgun reloading powder measure.

Less suitable for: Handloaders requiring single charges exceeding 10 grains (such as mid-to-large capacity rifle cartridges), which require a universal/rifle powder measure with a 5 to 100 grains range or an intermediate 1 to 25 grains measure; reloaders charging sub-.22 calibre bores without an aftermarket drop tube; or any black powder dispensing applications due to static and spark hazards.
