Mec Powder Bushing #21 -

The MEC Powder Bushing #21 is a precision metering component designed for reloaders using MEC shotshell loading equipment. This powder bushing serves as the critical calibration tool that meters consistent powder charges into shotshell casings, ensuring shot-to-shot uniformity and safe, reliable performance. Whether you're a competitive clay shooter, waterfowl hunter, or dedicated hand-loader, the correct powder bushing is fundamental to producing ammunition that performs as intended downrange.

The #21 bushing is engineered to dispense a specific powder charge volume when installed in MEC's powder station, allowing reloaders to dial in their exact load recipes with precision. Each MEC powder bushing is manufactured to tight tolerances—this particular model (#21) corresponds to a defined charge weight on MEC's official Powder Bushing Chart and Charge Bar Selection guide. The bushing's internal geometry controls the rotary measure's cut-off point, directly determining how much powder enters each shell. Accurate powder measurement is non-negotiable in shotshell reloading; it affects velocity, pattern consistency, and safety. The lightweight design (0.05 lbs) makes it easy to swap between different bushings when changing loads or powder types.

Reloaders working with MEC progressive or single-stage shotshell presses will need the correct bushing for their intended load, and the #21 fits seamlessly into standard MEC powder measure stations. Because powder charge accuracy directly impacts ballistic performance and safety, cross-referencing your load data with MEC's official Powder Bushing Chart ensures you're using the right component. This bushing is essential for anyone committed to producing consistent, field-tested ammunition that meets their specific performance requirements and safe operating parameters.
