So the power drop flaring die is where you set it to where the bullet can set in the brass and then when you seat it, you should not scrape any coating off of the bullet.
Next step is taper crimp and final step.
So after I seat my bullet to my OAL, overall length, the next station is a LEE factory taper crimp die. I would run your ram all the way up until the die is just touching your shell plate, or a couple thousandths away. For the taper crimp there is a adjustment knob you turn in and out for how much taper crimp you will set. back it out a couple tuns. Seat a bullet and run it up into the crimp die. Leave it there while your ram is all the way up. Turn the adjustment downward until you feel it touching the bullet, you should feel it hit. Drop the ram down slightly and turn the crimp adjustment in one half turn, then run the bullet back up into the die and you will feel light pressure and you should see a difference. It's something that you have to play with to find the right amount of taper. But with a blue bullet you do not want a heavy taper on the bullet.
