MEC Re-size Ring for 600JR – 12ga #846512 The re-size ring is a wear item located on the depriming station of the MEC 600 Junior re-loaders. After repeated use, this part will wear and break or it may not fully re-size hulls down to proper specs. For best re-sizing performance, this part should be replaced every so often, depending upon your reloading volume. If you are having trouble with re-sizing your hulls, you may want to use the MEC Super Sizer. This is a terrific alternative to the 600 JR’s re-size ring.
