Congrats on your purchase of a Super Blackhawk-I have 1 exactly like it. In regards to self defense loads, I seriously doubt it matters which jacketed load you use, it's a .44mag-MORE than enough oomph regardless of which you choose. That's assuming you meant defense against humans. The only thing you have to worry about is gross overpenetration through walls. For defense against critters such as bears I'd choose some hardcast bullet loads.
Sometimes you earthlings REALLY amaze me!
