MEC Powder Bushing #37 Size

The MEC Powder Bushing #37 Size is a precision reloading component engineered for both progressive and single-stage charge bars. Manufactured from aluminum by Mayville Engineering Co., this bushing delivers the tight tolerances and repeatability critical to consistent ammunition loading. The #37 size accommodates a wide range of powders, making it an essential part for high-volume reloading operations and shooters who demand load-to-load consistency.

MEC powder bushings are held to strict quality-control standards during manufacturing. The aluminum construction keeps weight minimal while maintaining the dimensional precision required for reliable powder charge drops. This particular bushing is available in a range of sizes to match different powder granule profiles and loading scenarios. Reloaders who run high-volume sessions appreciate having backup bushings on hand, as worn or damaged components can introduce variability into the powder charge weight—a critical variable in ballistic performance and pressure consistency.

The #37 bushing is suited for serious handloaders—both competitive shooters focused on precision and hunters who standardize their own ammunition. It serves as a direct replacement for worn or lost bushings and is competitively priced relative to OEM alternatives. Whether you're running a progressive loader for high-volume pistol rounds or using a single-stage press for rifle loads, having the correct bushing size eliminates guesswork in powder charging and supports the meticulous approach that quality ammunition demands.
