That is correct. More people have died from 22lr gunshots than any other caliber. (might be more than all others put together, do not remember the stat).
Come at someone holding a 10/22 or a Ruger MK II, and you will quickly be leaking from 10 or more new holes.
A gun is not some kind of magical instant death machine. Not like the movies, at all. It takes disruption of CNS to incapacitate quickly, otherwise, it is due to low blood pressure from blood loss.
The Miami Shootout guys were mortally wounded early in the fight, but kept on fighting.
The Mossad used Bereeta 70 in.22lr for decades
