Are you sure you have the right die? I use the Lee FC die for my 223 and it contacts the shell holder before the ram is at the top of it's stroke. As it continues, the crimping process begins as the collet is squeezed into the neck of the cartridge. If your "die" doesn't contact the shell holder you may have the wrong die or your round is too long (OAL).
My definition of Gun Control--- A steady grip and hitting your target.
