The MEC Resize Ring in .410 gauge (MEC part no. 435410) is a replacement wear part for the depriming station on MEC 600 Jr shotshell reloaders. High-volume reloaders eventually wear these rings down to the point where they crack or stop fully resizing hulls back to spec, so keeping a spare on hand avoids a mid-session stall. MEC recommends replacing the ring periodically based on reloading volume, and if resizing issues persist even with a new ring, the MEC Super Sizer is a step-up alternative.

Frequently Asked Questions

Why would I need a spare resize ring? These rings wear down with reloading volume and can eventually crack or stop resizing hulls fully to spec, so a spare avoids a stall mid-session.

Is there an alternative if resizing issues continue? Yes, if resizing remains a problem even with a fresh ring, the MEC Super Sizer is a step-up option.
