I have a Hollywood .223 die marked 'TC' which I assume is carbide. Also it appears the actual sizing portion of the die is pressed in the body which again I assume is made of Tungsten Carbide. The problem is it does not 'act' like a TC sizer in that the cases do not run smoothly through it and I have had to pull two stuck cases from it after I pulled the rims off the cases. Lubing the cases solves the problem but negates the original reason for a TC die. Any help will be appreciated.
