Which powder measure models are compatible with the Lee Precision 90792 Adjustable Charge Bar?

The Lee Precision 90792 is specifically engineered as a direct drop-in replacement for standard fixed-cavity disks in both the Lee Auto-Disk and Lee Pro Auto-Disk Powder Measures. It is widely used by Australian reloaders on progressive and turret press setups like the Pro 1000 and Classic Cast Turret to allow stepless adjustments.

What is the exact volumetric capacity range and how is it adjusted on this charge bar?

This charge bar features an infinitely adjustable volumetric cavity ranging from 0.28 cc to 1.6 cc. It utilizes a solid brass, zero-backlash micrometer with thimble markings graduated in 0.1 cc increments, allowing you to easily dial in exact mid-step charge weights between standard pre-set disk sizes.

What are the limitations if I need to drop powder charges larger than 1.6 cc?

The operating envelope of the 90792 is strictly capped at an upper threshold of 1.6 cc, which roughly equates to about 16 grains depending on the powder's density. For larger charges exceeding this limit, you will need to use an alternative tool such as standard large Auto-Disk cavities, a Lee Double Disk Kit, or an Auto-Drum Powder Measure.

Does this mechanical reloading accessory require any electrical compliance or SAA/RCM certification in Australia?

No, electrical compliance and SAA/RCM certifications are not applicable to this product. The Lee Precision 90792 is a completely manual, unpowered mechanical accessory crafted from lifetime nylon and solid brass, requiring no 240V mains power or electrical plugs for operation in your reloading room.

Adjustable Charge Bar - Lee Precision 90792

The Lee Precision 90792 Adjustable Charge Bar is a mechanical volumetric powder metering accessory designed to replace standard fixed-cavity disks in Lee Auto-Disk and Pro Auto-Disk powder measures. Engineered with an injection-moulded nylon body and a solid brass micrometer mechanism, this drop-in bar provides continuous, stepless volumetric adjustment. It allows handloaders to calibrate precise intermediate charge volumes without modifying factory hardware, making it ideal for progressive and turret press reloading setups.

Key Features

Who is the Lee Precision 90792 Adjustable Charge Bar for?

Handgun reloaders — Provides continuous volumetric metering across an adjustable range of 0.28 cc to 1.6 cc to dial in exact powder charges for calibres such as 9mm Luger, .38 Special, and .45 ACP using this adjustable powder measure charge bar.
Small-capacity rifle reloaders — Features a micrometer graduated in 0.1 cc marks on the thimble, allowing handloaders to set precise mid-step charge weights up to a 1.6 cc maximum volume without swapping fixed cavity disks.

Less suitable for: Reloading applications requiring powder charges greater than 1.6 cc; volumetric powder measures designed for large rifle charges, double-disk stacking kits, or dedicated rotary drum powder dispensers are better suited for higher-volume loads.
