MEC Powder Bushing #13A Size

The MEC Powder Bushing #13A Size (part number 05013A) is a precision reloading component manufactured by Mayville Engineering Co. and engineered for high-volume ammunition reloading operations. This aluminum bushing delivers consistent powder metering across progressive and single-stage charge bars, making it an essential replacement part for reloaders who demand accuracy and reliability in their cartridge assembly workflow.

MEC bushings are manufactured to tight tolerances with precision engineering and quality-control protocols that ensure repeatability in powder charge measurements. The #13A size accommodates specific powder types and load ranges, and the aluminum construction balances durability with the smooth operation required for trouble-free indexing through multiple reloading cycles. This bushing is compatible with both progressive and single-stage charge systems, offering flexibility across different reloading platforms and methodologies.

Serious handloaders—whether preparing ammunition for precision rifle competition, law enforcement training qualifications, or high-round-count field operations—maintain an inventory of replacement bushings to minimize downtime during extended reloading sessions. Having the correct bushing size on hand prevents workflow interruption and ensures consistent powder charge delivery across large batches. The #13A is specifically sized for applications where standard-range powder measures require reliable metering without calibration drift across hundreds of rounds.

MEC has built its reputation on component-level precision in reloading equipment. Even small parts like powder bushings receive the same rigorous manufacturing standards and quality inspection that serious reloaders expect when processing ammunition to match their firearm's specifications and their shooting requirements.
