The MEC Super Sizer, .410 Bore (MEC part no. 8119410) re-sizes fired .410 bore shotshells back down for the tightest, most exacting chambers, using MEC’s exclusive Power-Ring collet resizing device instead of a standard single-ring sizer. Eight steel fingers encircle the shell base and apply even pressure until it returns to its original dimensions, a step up from the basic resizing built into most shotshell reloaders.
