Bluedot37- It seems to work best at higher pressures. While there is cast bullet data available for Power Pistol, there is not an abundance of it and cast bullets are about all I use in handguns. My notes indicate some relatively accurate Power Pistol loads, but it appears I always found a powder that worked a little bit better. I haven't bought any Power Pistol in quite a while.

Maybe its best use is with jacketed bullets, but I don't have the experience to comment on that. Regardless, I'd still call it a specialized powder.
