a. Put the shellholder with cartridge back into the press.
b. Remove the die.
c. Raise the ram until the bullet itself comes through the top.
d. With a pair of vise grips or channel locks (yes, you're going to ruin the bullet) clamp onto the bullet HARD, and lower the ram. The bullet will separate.
This is my method for pulling ANY cast bullet, since I can just remelt it and make it like new again. It's also faster than using an inertial puller if you don't care about saving the bullet.
