Just received my 7mm neck sizer, it is a redding and is the same as my full length and seater, the instruction were unclear in my mind as to how to set it up. Per Nosler it states to allow 1/8 between top stroke and bottom of sizer, per redding you set it up just like a full length with the top stroke touching the sizer. Any suggestions, advise from the pros. Hopefully this will let me get more use out of the brass. Thanks Steve
