Mec Powder Bushing Number 14 5014. When the hopper is full there is a slight pressure build up inside the bushing which pushes the powder through the charging bars. Over time this pressure causes the bushing to wear and lose efficiency. To prevent this from happening MEC has created a better bushing that will easily fit in the charging bar of your MEC exclusive rotary charging system. Mec Number 14 Powder Bushing can be used for a wide range of calibers and sizes of powder charges.
