If I ever figure out how to work this one die, I hate to think about the next stage which is supposed to "bell" the case neck and dump the powder. Even more I don't want to mess with the third die that seats the bullet and makes the crimp.
Before we go any farther, what cartridge and type of dies are you useing? It sounds like you`ve a 3 die set, correct? Is the case a straighwall or bottleneck? 3 die sets are normally for straight walled brass not bottle neck. There should be a sizer/decapper and seater/crimper if they are bottleneck dies. Belling isn`t done on bottle neck cases.
