The other problem is that Super Vel played on the supposedly reliable findings of the NIJ and its Relative Incapacitation Index (RII), which emphasized the temporary wound cavity, which said that light, fast bullets out-performed all loads. This wasn't the experience of folks in the real world, but because it was based on computer models and high tech stuff, many people ran with it.

Once the light, fast theory was disproven (again), people went to bigger calibers.

Even now, the loads that were the big deal with Super Vel and the NIJ are not what is shown to be the best performers in the FBI ammo tests.

Now, if anyone wants to dispute the FBI tests, that is fine with me, but I will take proven loads over a box label and nostalgia. Everyone else is free to have their own opinions.
