I bought a new Sinclair Case Neck Sorting Tool and 100 new pieces of WW brass for a 300 WM. Everything I have read says to sort the brass by neck wall thickness before going through a sizing die. Most of the case necks are slightly dented and none of them will fit over the pilot for the tool. I would think it should be o.k. to run them through a sizing die and still get an accurate reading. Does this sound right?
