Can you be more specific as to what you did with your FL die?
There really isn't a lot of "Messing" that can be done to get FL sized brass to chamber.
Basically, screw the die into the press until it contacts the shell holder.
Lower the ram and screw the die into the press 1/4 turn More.
Lube and size a fired case. See if it chambers and extracts with ease. If yes, your are done Lock it down and double check. If No, screw the die into the press a little at a time until it does chamber.
