I am using RCBS "Cowboy" dies for reloading the 32-20 Winchester. New brass is Winchester, cast 100gr lead bullets over 3.0gr of Titegroup. The problem comes with using the expander die. I can not get the right expand for seating the bullet. If the case flares out it does not seat in the chamber all the way. The seating die does not crimp the bullet. Without the expander die the case crumbles under the bullet. I have tried re-running the flared cases back thru the sizing die but it does not reform the case and remove the flare. 11 cases later I am frustrated, to say the least. Time to quit and breakout the Jack!? What am I doing wrong? Help.
