I read an interview with a doctor who worked the ER in a busy hospital in a violent urban center.
He stated that .22s fragment badly in a body and cause wounds silimiar to HE shrapnel- very difficult to find all the pieces or repair the damage- so the victims tend to die later rather than than sooner.
I would find another surgeon as what he says doesn't jive with reality. Does any of that make sense that a relatively low velocity small projectile would cause HE-like wounds. Did he explain the mechanism by such a tiny, underpowered round exhibited such remarkable capabilities? Did he also talk about how .22 lr inside a head will just ping pong back and forth off the insides of the cranium until the brain is soup? That is something I have heard several times in the past also purportedly from surgeons lamenting how the .22 lr is so much more deadly than other calibers.
There is NOTHING about a .22 that causes it to fragment badly in the body unless you have frangible round or that it hits bone, particularly heavy bone, but that goes for just about any bullet, right?

...where .22 and .25 weren't nearly as lethal as the non-High Explosive rounds being fired like 9mm and .45 acp.
He really said .22 lr wounds look like HE wounds? Had he ever seen an HE wound?
I am sure .22 lr fragments are hard to find just like with other bullets fragment. That is why they have X-rays and when the fragments are really tiny or difficult to remove, sometimes some get left behind, regardless of caliber.
Whenever I read medical journal info on ballistic wounds, I never seem to find any mention of the HE nature of .22 lr wounds. I wonder why that is?
There is nothing magical about .22 lr expect some people's opinions of it. It may be underrated by some, but it is definitely overrated by others.
ANY PROJECTILE THAT HAS THE CAPABILITY TO PENETRATE SOFT TISSUE IS DANGEROUS AND COULD BE DEADLY. THOSE THAT PENETRATE MORE THAN A JUST A FEW INCHES CERTAINLY MAY BE DEADLY, BE IT A BB GUN OR .50 BMG. A lucky hit on a near surface major blood vessel can result in death with a fairly minor injury. The issue of death isn't so much a caliber issue, but a biological one. The link between caliber and lethality is tissue damage. By and large, .22 lr tend to produce less tissue damage than larger calibers (.25 acp being a possible exception).
