OK, back to the topic of .357 Magnum...
Although the .357 Magnum HST and Silvertip data above is similar, the HST is a bit better. Add to that the obviously better bullet design and function, and the HST would make a better choice for self defense. I would change my vote, if possible, to reflect my thoughts.
I am seeing the .357 Magnum HST available on about 30 websites. I am considering a purchase.
