The MEC #46 Powder Bushing (MPN 5046) is a precision-machined bushing built by MEC Reloading to calibrate propellant charge weight in MEC single-stage and progressive shotshell reloading presses. Installed inside the charge bar of a compatible MEC press, bushing #46 meters a specific volume of powder on every stroke, letting reloaders dial in a consistent, repeatable charge without weighing every load on a scale. It’s a wear item every high-volume shotshell reloader eventually replaces or adds to a bushing chart, and MEC’s numbered system makes matching bushing to load recipe straightforward. It’s an inexpensive way to keep charge weights consistent from box to box.

Key Specifications

• #46 bushing number, matching the number stamped on the part to standard MEC bushing charts for repeatable charge selection.
• MEC single-stage and progressive charge bars compatibility, meaning it drops into the existing charge bar without additional tools.
• Powder metering application, sized for calibrating propellant volume rather than shot charge weight.

Frequently Asked Questions

What does a MEC powder bushing do? It calibrates the volume of propellant your MEC single-stage or progressive shotshell press drops into the case on every stroke, so bushing #46 delivers a consistent charge without weighing every load.

Will bushing #46 fit any MEC press? MEC’s charge bar system is standardized across its single-stage and progressive presses, so a bushing of the correct number drops into the charge bar of any compatible MEC reloader.
