I got bored ans attempted to build a .452 bullet.
I used my Lee .451 sizing die to size down a 45acp case. I then filled it with molten lead. Next I used a 260 Remington Seating die to form the nose. After that I used my Lee 45acp seating die to finish closing the nose up. The result came out at 344.1 grains and looks like this.
