There are many loads for both of these in many manuals. Probably more for Bullseye than PP as I think it has been around longer. I believe Bullseye was developed specially for the 45 ACP if I am not mistaken. I think Bullseye is a faster burning powder than PP so it will normally require less powder per load comparatively to PP.
I used Power Pistol today in my 357 Mag and I really liked it. I loaded it under a 180 grain Hornady HP/XTP. I liked it much more than 2400 as it seems cleaner and easier on the gun. I have used Bullseye as well, and it works well but it seems less tolerant to measurement inconsistencies, and it builds pressure real fast
I am going to do some more experimenting with Power Pistol in my 9mm, 40 S&W and more loads for my 357 mag, but so far I like what I see. It looks to work well for low velocity target plinker loads and works well on cranked up full house magnum hunting loads as well.
Have fun and be safe.
