The Redding Imperial Bio-Green Case Lube (MPN 07300) is a super-duty liquid lubricant engineered to reduce friction during full-length cartridge resizing and heavy brass forming operations. Formulated entirely from plant-derived, biodegradable ingredients, this petroleum-free liquid eliminates brass staining and cleans up easily using plain water or an ultrasonic bath without the need for harsh solvents. Supplied in a 3 fl oz bottle, it is designed for use with standard pad-type applicators or direct fingertip application across all rifle and pistol calibres.

Key Features

• Plant-Based Formula: Made from 100% petroleum-free, biodegradable ingredients, providing a non-toxic alternative that will not discolour brass cartridge cases.
• High-Pressure Lubrication: Engineered for super-duty full-length resizing and brass forming, preventing stuck cases and brass deformation inside standard steel or carbide dies.
• Water-Soluble Cleanup: Rinses away completely with standard tap water or inside ultrasonic cleaning baths, removing the need for petroleum-based degreasers.
• Flexible Application: Formulated specifically for batch application via standard reloading lube pads or direct manual fingertip coating.
• Universal Brass Compatibility: Safe and effective for sizing all small, medium, and large rifle and pistol cartridge cases.

Who is the Redding Imperial Bio-Green Case Lube for?

• Precision rifle reloaders performing full-length case sizing — requires a dedicated, water-soluble case sizing lubricant supplied in a 3 fl oz bottle that prevents stuck cases during heavy press strokes and washes off cleanly without petroleum solvents.
• Reloaders processing wildcat or reformed brass cartridges — benefits from a high-pressure, plant-based liquid case lubricant packaged in a 3 fl oz volume that delivers high-film-strength protection during intensive dimensional brass reforming on a lube pad.

Less suitable for: High-volume progressive reloading of bulk brass where spray-based alcohol-lanolin lubricants allow faster batch coating than pad-applied liquids, or extreme single-case wildcat shoulder setbacks and severe reforming operations where a solid sizing die wax is preferred.
