I purchased a nice used .100 short 22ppc barrel from a good friend of mine and i am going to have my father cut the dies down for me. My Dad is a tool maker for GE and this shouldnt be any trouble for him to do. I just need to know EXACTLY how much to cut off the bottom of my Wilson seat die? Do we cut EXACTLY .100 off or .098 or .102 or other? I would assume .100 EXACTLY but you know what they say about assuming anything. This is all new to me so i just simply dont know. I am sure some of you guys have done this before so i was hoping for some info. I am going to have Harrells make the FL Size die so i am not worried about that, just the seat die. Are these Wilson seat dies hard steel? will it require any special cutting tools? Any info along these lines is much appreciated. Thanks fellas! Lee
