What press models are compatible with the Hornady #390 Powder Bushing?

The Hornady #390 Powder Bushing is specifically designed to fit the charge bars of the Hornady 366 Auto progressive shotshell press and legacy Hornady Apex loaders. Please note that it is not compatible with standard Hornady Lock-N-Load metallic powder measures, which use different rotor inserts.

What powder charge weights can I expect when using the #390 bushing?

The #390 bushing features an exact internal diameter of 0.390 inches. According to Hornady factory charge charts, this volumetric size typically drops approximately 15.0 grains of Hodgdon Clays, 18.0 grains of Universal, or 21.0 grains of Hodgdon HS-6, though actual weights will vary based on powder lot density and operating vibration.

Are there any Australian electrical or regulatory compliance requirements for this product?

No. The Hornady #390 Powder Bushing is a completely unpowered, solid-metal mechanical reloading component requiring no electrical connection. Therefore, 240V compatibility, SAA/RCM certifications, and electrical safety approvals are not applicable to this item.

Powder Bushing - Hornady 190147

The Hornady #390 Powder Bushing (MPN: 190147) is a drop-in volumetric metering insert designed for progressive shotshell reloading charge bars. Machined to provide a fixed internal capacity, it swaps directly into compatible charge bars to eliminate manual powder cavity adjustments during high-volume production. Operating via gravity and press agitation, the bushing dispenses consistent propellant charges based on powder density. Depending on the selected propellant, reference dispensing values for the #390 include approximately 15.0 grains of Hodgdon Clays, 18.0 grains of Universal, or 21.0 grains of Hodgdon HS-6, with final charges verified using a calibrated scale.

Key Features

Fixed Volumetric Cavity: Features an exact inside diameter of 0.390 inches (approximately 9.906 mm) to meter propellant charges consistently across continuous loading cycles.
Interchangeable Drop-In Design: Fits directly into progressive charge bars, allowing loaders to change powder charges by swapping bushings without altering press settings.
Multi-Gauge Utility: Meters propellant charges suited for reloading 12, 16, 20, 28 gauge, and .410 bore shotshells.
Mechanical Operation: Fully unpowered, mechanical solid-metal component requiring no electrical connections or calibration electronics.

Who is the Hornady #390 Powder Bushing for?

Hornady 366 Auto press operators — installs directly into progressive shotshell press charge bars to drop an exact volumetric charge using its 0.390-inch inside diameter without requiring micrometer adjustments.
Competitive clay target reloaders — dispenses consistent target loads across 12, 16, 20, 28 gauge or .410 shells, dropping approximately 15.0 grains of Hodgdon Clays or 18.0 grains of Universal to maintain uniform velocity during sustained shooting runs.

Less suitable for: Metallic cartridge handloaders using standard Lock-N-Load case-activated powder measures; these measures require adjustable metallic powder measure rotor inserts or manual trickle-dispensing systems rather than fixed-diameter shotshell drop bushings.
