You can get data for them from Hornady's website. Exclusive to that bullet. If you load for a Handi, you are going to be better off from us lever gun guys because you can use a longer OAL. If you use the longer OAL and couple that with some of the "Thompson Only" loads, or Linebaugh's loads for the ol' Colt, you are going to have a humdinger of a 45Colt carbine on your hands!
If you go with an OAL that Hornady suggests, remember, they are living by the lever gun cycling length and you most likely will have to trim cases to get there.
Maybe not for the 200gr, for their 250gr, I know that you have to.
