  Depends on how precise you want to get.
  You can roll the loaded round across a piece of glass and watch to see how much "tip wobble" there is
  You can mount the case in a test stand and measure the bullet runout with a dial indicator
  
  In either method, the actual runout (off center) is 1/2 of the measurment (TIR)
