MEC Lock Nut #460A
Original MEC replacement part.
Resizing high-brass hulls: If you are experience resistence when resizing high-brass hulls, try just a little bit of Mica Wad Slick on the brass, die, or resizing area of your reloader. A little dry lube goes a long way toward saving reloading sanity. Also, the MEC Super Sizer works very for all high brass hulls.
