Hey fellas I have a question, I am new to reloading 9mm and I have acquired a Tungsten Carbide sizing die but when using it I noticed that it sizes the cases 0.010 smaller at the base when compared to my regular 9mm sizing die. Is there something wrong with this die? I called Lyman and the woman just told me “ get another one”. So much for customer service. Below are 2 pics showing what is happening. The case on the left in both pics are using the regular Lyman die and the case on the right in both pics are of the Lyman TC die.
