Located at the depriming station of the MEC 600 Jr. reloading press, MEC resize rings are critical components for reshaping spent hulls back to proper specifications. Over time and with frequent reloading, these rings can wear out or break due to the constant mechanical stress of resizing. Additionally, even before failure, some reloaders may find that the rings begin to lose their effectiveness, leading to improperly resized hulls that could impact overall reliability and cycling. For dedicated reloaders who operate at high volumes, having spare resize rings on hand is a practical and proactive solution. MEC recommends periodic replacement of these rings based on use frequency to maintain peak performance. If consistent resizing remains problematic despite new rings, the MEC supersizer offers a viable alternative for achieving precise resizing results with enhanced consistency.
