Yep, STORMINORMAN, it's Bullseye in the competitive sense. I asked an open-ended question so as to not "lead the witness."

I'm OK with picking powders/charges from my stash and then working up some loads the way I've done for quite some time. For "powder puff" loads, I figure a faster powder like Clays or Titegroup or maybe the old standby Bullseye would be a good place to start. As for bullets, I'm thinking the 0.356" diameter might be a better choice. I've heard people have used 9mm (0.355") or 38/357 (0.357") bullets successfully.

I'm keen to hear about lessons learned from people who have gone down this path successfully or even unsuccessfully.
