“Let us say that any representation of super hot loads will be tested against a ballistic gelatin matrix “
Uh, no. DA’s offices don’t even bother with gelatin. That doesn’t prove a “hot load” velocity. Only a chronograph can do that, and I don’t know a DA’s office or a crime lab with one. Bullet velocity simply has never in any case been an issue.
And will not be an issue as the remaining bullets can be tested with chrony or gelatin. Which is my point that super hot loads are testable they are not some imaginary bogeyman that can be thrown about willy-nilly by the DA.
