I tried some cast 9mm bullets once. They were from a Lee mold, round nose and were about 125 grains. I used a little more Bullseye than you did, somewhere around 3.0. Because there was no groove on the bullet, the crimp was very light. I could not have put a heavy crimp on them if I had wanted to.
They shot very well, although I didn't try them on squirel sized targets. Good shootin'.
