There is no need for anything when I use the full sizing die but the smooth sizing die or, just knurled to fit, will leave a lot of gas leakage until or even if the bullet obturates.
I have always been somewhat concerned about cutting the petals. Not sure I could cut them off equally. I worry about creating an unequal amount of pressure one place or another might cause some deflection in the bullet.
Depending on which bullet you use you might not get any or very little obturation.
