“Must” was too strong a word. Let us say that any representation of super hot loads will be tested against a ballistic gelatin matrix and the results entered into evidence with an opinion stated to the jury.

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.
