Mec Powder Bushing #39 -

The MEC Powder Bushing #39 is a precision metering component designed for reloaders who demand accuracy and consistency in ammunition assembly. Whether you're a competitive shooter, precision rifle enthusiast, or high-volume handloader, this powder bushing serves as the volumetric regulator in MEC reloading presses—controlling the exact charge weight of powder that enters each case. For anyone serious about shot-to-shot consistency and repeatability, selecting the correct powder bushing is as critical as choosing your powder and primer combination.

The #39 bushing is engineered to meter specific powder charges by controlling cavity volume within the MEC reloading press's powder station. Each bushing number corresponds to a unique internal cavity size, allowing loaders to dial in precise grain weights based on their load data and powder type. The compact, durable construction—weighing just 0.05 lbs and measuring 1.5 × 1.15 × 4.55 inches—ensures reliable engagement with MEC press mechanisms while maintaining dimensional consistency across every reloading cycle. Referencing MEC's Powder Bushing Chart and Charge Bar Selection guide ensures you're matching the correct bushing number to your specific powder and desired charge weight, eliminating guesswork and reducing the risk of over- or under-charged rounds.

Reloaders using MEC single-stage, progressive, or semi-progressive presses will find the #39 bushing essential for maintaining load integrity and ballistic consistency. This component is compatible with all standard MEC press platforms that accept interchangeable powder bushings, making it a critical spare or upgrade for bench setup optimization. Proper bushing selection directly impacts velocity spreads, group consistency, and overall ammunition quality—factors that separate sub-MOA loads from mediocre rounds downrange.
