To do that level of damage requires a bit more than even a high velocity

There has been a good deal of development over the years to get reliable
expansion. Even the .22 LR has seen improvements.

CCI worked with the FBI spec ballistic gelatin to get reliable expansion.
The rounds don't expand in the more popular clear gelatin so it comes down
to which test more accurately represents the human body.  They are a far
cry from .223 rounds but make .22 LR a little more feasible for self
defense.

Even the traditional lever action calibers have seen work to improve their
performance and overcome the restrictions of tubular magazines.
