I know that it has been some time since you post, but I have the best results with 231 (when I can find it anymore) CCI small pistol primers or CCI large pistol primers seem to work great for me. I used a lighten up crimp and load to Min OAL, which is risky if you overload or seat too deep. But I like those loads. I use the cheap brands of bullets, E-treme or Ranier.
