Mec Powder Bushing Number 10 5010M. The number 10 bushing works in a progressive charging bar and single stage charging bars. This bushing prevents powder from being knocked out of the charge bar unless the load is very light like a slug load. The MEC Powder Bushing helps prevent powder from being knocked out of the charge bar. This bushing also acts as a check that prevents charging bar and spout breakage. The MEC Powder Bushing helps achieve a smooth powder-flow in a single session which saves wear and tear on the bar and bushing. Because this bushing is so small it can easily be misplaced during a single session. However please understand this bushing is only a bushing and should not be confused with a MEC Custom Grade powder bushing which is a much larger item.
