sdb conversion change

Hello, I have recently just got into reloading and purchased the sdb.  The press came with .45acp already installed and I successfully made around 500 bullets.  However, when I went to change from .45 to 9mm I am having some issues.  When the press goes to stage 2 (powder drop) it is expanding my case out immensely.  As I said, I am new and I have probably just did the changeover in-correctly.  I replaced toolhead, dies, and primer slide.  Do you have any advice as to what it could be?

Thanks,

Mike

I didnt describe the problem very well, the problem is with the flare.  it looks as if it is flaring out for a .45 but i changed this.  Why is it flaring so big?  thanks.

It sounds like the powder die in station two is set down too far. Be sure you have the "F" funnel inside the die- the funnel for 45 is marked "E". If the F funnel is installed, then back the powder die up until the case is only flared .010-.020".
