I settled on Longshot for that application in Ruger BH 45 Colt. 13 grains gets me a bit over 1200 fps. Slower burners allow for quite a bit more speed if you want it, but the charge weights are a lot higher for the same level of performance as Longshot, and cause recoil to be noticeably greater for nearly the same velocity, IME.
