Mec Powder Bushing #34 -

The MEC Powder Bushing #34 is a precision metering component designed for reloaders who demand consistent powder charges across every round. This bushing works within MEC's automated powder dispensing systems to control volumetric powder measurement with repeatable accuracy. Whether you're handloading rifle or shotgun ammunition, selecting the correct powder bushing size is critical to achieving uniform velocities and ballistic performance—directly impacting accuracy and reliability downrange.

The #34 bushing functions by rotating through MEC's powder measure cavity, mechanically dispensing a fixed volume of powder with each stroke of the reloading press. The bushing's internal geometry is engineered to match specific powder types and desired charge weights, ensuring that each cavity fills consistently without bridging or settling. Because powder charge uniformity directly correlates to case pressure, muzzle velocity, and shot-to-shot velocity spread, choosing the exact bushing size for your powder is non-negotiable for precision handloading. MEC provides a detailed Powder Bushing Chart that cross-references powders, desired charges, and corresponding bushing numbers—the #34 covers a specific range within that spectrum.

The MEC Powder Bushing #34 is essential for shooters running MEC reloading equipment—including progressive presses and single-stage setups with MEC powder measures. Before installation, consult MEC's official Powder Bushing Chart to confirm that #34 is the correct size for your specific powder type and target charge weight. Proper bushing selection eliminates the guesswork from powder metering and ensures that every round leaves the press with identical charge weights, translating to tighter groups and predictable performance on the range or in the field.
