Mec Powder Bushing #9 -

The MEC Powder Bushing #9 is a precision metering component designed for reloaders and ammunition enthusiasts who demand consistency and accuracy in their handload production. This small but critical part serves as the volume-measuring element in MEC reloading equipment, allowing shooters to achieve repeatable powder charges across large batch runs. Whether you're loading rifle or pistol ammunition for competition, hunting, or range practice, selecting the correct powder bushing ensures your reloads meet tight tolerance standards and deliver predictable ballistic performance.

The bushing operates as a cylindrical volume selector within MEC's progressive or single-stage presses, creating a precisely calibrated cavity that meters a specific charge weight from your powder supply. Each bushing size is engineered to dispense a particular volume of powder, and the #9 designation corresponds to a specific charge range detailed in MEC's comprehensive Powder Bushing Chart and Charge Bar Selection guide. Weighing just 0.05 pounds with compact dimensions (1.75 x 0.9 x 4.55 inches), this bushing is constructed to tight tolerances to prevent powder bridging, ensure consistent throw weights, and deliver shot-to-shot uniformity that directly impacts accuracy at distance.

Reloaders who operate MEC equipment—from the 600 Jr. to advanced progressive systems—will find this powder bushing essential for caliber switches and charge adjustments. Before installation, consult MEC's official Powder Bushing Chart to confirm that the #9 specification matches your intended powder type and desired charge weight. Proper bushing selection eliminates over-charges and under-charges that compromise velocity consistency and pressure curves, making this small component a fundamental tool for anyone serious about ammunition quality control and reproducible ballistic data.
