Being the Luddite that I am, I hold the view that we don't really enjoy quite the increased efficiency of the results of "expanding bullet technology" that we collectively think we do and it's still up to shot placement.

The "super-bullet du jour" that is chased incessantly by a generation of shooters is more marketing than super-bullet.

I also hold that there hasn't yet been made the .32 ACP cartridge that even comes close to the .45 Colt.
