I have the S&B soft points. They have a heavy slug, Flat point, and supposedly flatten somewhat. I don't know if that's true, I haven't shot them into a medium to see, but they do shoot nice and straight from my model 10 and they should at least penetrate as much as a SWC loaded to standard pressure. I wouldn't hesitate to use them for self defense if JHP's weren't available. I don't know if it was a hollow point design that expansion would be guaranteed at slower velocities anyway.
