MEC Resize Rings Features The MEC Resize Rings are located directly on the depriming stations of the MEC 600 Jr reloader a critical point in the reloading process where hulls are resized back to proper dimensions for reliable chambering. Reloaders who run high volumes through their press will naturally wear down these rings over time and because they are a wear item having spares on hand prevents an unexpected press shutdown mid-session. Worn rings can also fail to completely resize hulls to the correct specification leading to chambering issues or inconsistent shell dimensions that affect reliability in the field or at the range. Replacing these rings proactively rather than waiting for a failure keeps the reloading process running smoothly without unplanned interruptions. Sized specifically for .410 gauge shotshells these rings are a precise fit for reloaders working exclusively in that gauge on their MEC 600 Jr press. The manufacturer recommends replacing these rings periodically based on reloading volume treating them as a routine maintenance item rather than a one-time purchase. For reloaders who find that resizing has become inconsistent or unreliable even after replacing these rings MEC also offers the Supersizer as an alternative solution for more demanding resizing needs. Keeping a stock of MEC Resize Rings on hand is a simple low cost way for .410 gauge reloaders to maintain consistent press performance.
