Either you like to read old books/magazines or you're some past the spring chicken stage. It's been many years since the reverse loading of HBWCs was somewhat fashionable.
The HBWC will expand reliably as long as it is pure lead - most especially when loaded base up. At the velocities you could drive them from a 2 or 3 inch barrel I'd question their ability to adequately penetrate heavy clothing or bone.
My speculation is that center hits to the chest or adominal cavity would produce a very ugly, and likely deadly, wound cavity - but not an instant stop because of the lack of CNS involvment.
Another old timer that was reputed to be very deadly at close quarters (but again not necessairly an instant stopper) was the old .38 short with the 200 grain lead RN bullet. It was loaded in this country as the .38 S&W "Police" load. It was also a British military load for a while. IIRC from reading about it, they were very pleased with it's combat performance in Africa.
Apparently it's success derived from the fact that it moved out at around 600+ fps and was barely (if that) stabilized and when it hit it had enough weight to penertrate and at the same time tumbled quite a bit.
Years ago I had a j-frame .38 S&W with a 3 inch barrel. The 200 grain Police load was not at all difficult to control - even in that light a weight gun. I believe the mold for the 200 grain is still marketed, but I don't know of any commercial loadings in the modern .38 Special that would be equivalent.
I expect a comparison of the real world effectiveness of some of these "old timer" loads is not possible. Since no one uses them any more - where would you get the comparison data?
That said, I sometimes carry wadcutter loads in a lightweight j-frame. Partly because that is mostly what I have, and partly because what they can do to a bundle of soaked newspaper impresses me, and partly because I can control the gun better than when firing any of the new "super" loadings.
My guess is that from small short barreled handguns you can have either penatration or expansion, but not both.
