Read the thread from top to bottom. I am undecided.
Is the number of peopled killed by a caliber the gold standard of a cartridge? It seems the details the shootings would have to be analyzed by experts to tell. For example Nidal Hasan shot 42 people and killed 13 of those. Does that tell you anything of the effectiveness of the cartridge. He shot 214 rounds. That does not seem to add any information we can use. The engament lasted 10 minutes. He was shooting a pistol (5.7 x28) that has 20 round magazines. Now that might tell us a bit to analyze situation.
I am of the opinion that the pistol and the shooter mean more than the caliber.
