MEC Super Sizer Features The MEC Super Sizer uses eight steel fingers that encircle the base of a fired shotshell and apply even pressure until the base is reshaped back to its original dimensions. This even all-around pressure produces a more consistent resize than methods that rely on a single point of contact helping ensure shells chamber and extract reliably. Built from steel the Super Sizer is designed to withstand the repeated mechanical stress of resizing hull after hull across a long reloading session. For .410 bore reloaders properly resized shells are especially important given the tighter chamber tolerances common to that gauge. MEC s exclusive Power-Ring collet resizing device can be used to update a conventional reloading press with this more precise resizing method giving existing MEC reloaders a clear upgrade path. Reloaders who have struggled with sticky chambering or failures to extract will find that a properly resized hull solves many of those issues at the source. Because this tool is sold as a sizer only it is intended to complement an existing MEC reloading setup rather than replace it entirely. Shotshell reloaders working with .410 bore who want their hulls performing like new will find the MEC Super Sizer a worthwhile addition to their reloading bench.
