MEC Charge Bar Rubber Insert

The MEC Charge Bar Rubber Insert (MPN 8440) is a precision reloading accessory manufactured by Mayville Engineering Co. that enables fine-tuned powder charge adjustments during the reloading cycle. This rubber insert fits into the charge bar mechanism of MEC reloading equipment, allowing shooters to dial in exact charge weights for consistent, high-performance ammunition production. For handloaders pursuing sub-minute-of-angle accuracy and load consistency, this component addresses a critical control point in the reloading sequence.

Reloading ammunition requires precise volumetric or weight-based powder metering to replicate factory tolerances and ballistic performance. The charge bar system in MEC equipment relies on mechanical indexing to dispense powder charges; the rubber insert cushions and stabilizes the charge bar movement, reducing variance from shot to shot. Manufactured from quality elastomer materials, this insert maintains consistent performance across extended reloading sessions without degrading or losing compression. Proper charge bar function is essential for producing ammunition that groups consistently and performs reliably downrange, whether for competitive shooting, hunting, or precision rifle applications.

This accessory is intended for reloaders using MEC equipment who require replacement or maintenance of wear components. Over time, rubber inserts can compress or degrade, affecting charge consistency and press operation. Keeping a spare on hand ensures uninterrupted reloading capability and maintains the accuracy of your ammunition loads. MEC Charge Bar Rubber Inserts are a straightforward, cost-effective solution for maintaining the precision and repeatability your reloading press demands.

Ammunition reloading is a precise discipline; even minor inconsistencies in powder charge can shift point of impact or reduce velocity uniformity. Maintaining the condition of your press's mechanical and rubber components ensures that your technique and powder choices deliver consistent results.
