Over the years the removal of the Star sizing die has been frustrating for me. Using the Star Removal tool does require you to evacuate the last bullet from the die in order to pull the die out. So by removing the last bullet, you loose the critical point of reference for the bullet punch setup.
I find the easiest way to remove the die is not to use the tool that star/magma sends to pull it out. Instead I turned a piece of hard wood down which is just under the OD diameter of the die (.74"). I then drilled a .5" hole in the end for clearance for any bullet that might be in the die sticking out. When I am ready to remove the sizing die, I just push up with the dowel and it pops right out. Having the heater on makes this removal easier. Cold high temp lube kind of locks the die in place I have found.
The benefit of this is that is doesn't disturb the bullet inside the die as a set up reference. Also the hard wood dowel does not mar the machine or the die.
