The Redding Model 3 Powder Measure (Part No. 03200 / 03200R) is a manual, bench-mounted mechanical powder measure engineered for volumetric gunpowder dispensing across handgun and rifle reloading workflows. Built with a precision-machined cast iron frame, a hand-honed interior, and a hard chromium-plated drum, the unit reliably shears and meters extruded, stick, and flake propellants. This kit includes both a Universal Metering Chamber and a Handgun Metering Chamber, allowing reloaders to switch between small-capacity pistol loads and large-capacity rifle charges using standard front-facing micrometer references.

Key Features

• Dual Metering Chambers: Supplied with a Handgun Chamber metering from 0 to 10 grains and a Universal Chamber metering from 5 to 100 grains.
• Direct-Reading Micrometer: Front-facing adjustment provides clear reference markings to record and replicate verified powder charge volumes.
• Cast Iron and Chromium Construction: Features a hand-honed cast iron frame paired with a sharp-edged chromium drum to cut cleanly through propellants without binding.
• Standard Calibre Drop Tube: Includes a clear, see-through drop tube compatible with .22 to .45 calibre cartridge cases.
• Universal Bench Mounting: Machined with a standard 7/8"-14 thread interface and includes a dedicated mounting bracket to fit standard reloading bench stands.
• Mechanical Operation: Operates entirely manually with no electrical power, batteries, or digital components required.

Who is the Redding Model 3 Powder Measure for?

• Precision handloaders transitioning between rifle and pistol calibres — meters charges spanning from 0 to 10 grains with the dedicated handgun chamber up to 5 to 100 grains with the universal chamber, allowing a single bench-mounted powder measure to service small pistol and large rifle cases.
• Reloaders requiring manual mechanical powder measurement without electronics — uses a mechanical 7/8"-14 threaded cast iron assembly that operates without 240V mains electricity, battery power, or electronic components to dispense powder charges across .22 through .45 calibre cases.

Less suitable for: Handloaders charging cases outside the standard .22 to .45 calibre drop tube envelope (such as .17 or .20 calibre), or those dispensing charges exceeding 100 grains, who require dedicated sub-calibre drop tube adapters or high-capacity match-grade competition powder measures.
