The first book from Sanow indicated that the soft lead---non jacketed---158 grain HOLLOW POINT Semi wadcutter did best. They had soft lead that expanded well---the velocity from snubbies being relatively slow.

It is hard to find them from winchester and federal nowadays---but I have seen remington 's lately.

However---I would like to see some gelatin results with the Hornady FTX critical defense---especially the 90 grain.
