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.
Cartridges for police use are manufactured to do as much damage to humans as possible while keeping recoil low enough for fast, accurate follow-up shots (also for the most damage possible to a human being).
See the issues regarding 10mm, then .40 S&W. See recent changes in ammunition and bores for the more current and popular ar-15-type rifles (5.56 mm, 75 gr. Hornady TAP for law enforcement only, part #8126N, not the other one).
Manufacturers would make ammo for tiny, light weapons capable of blowing human targets to bits, if they could. They probably, eventually will, if no historical fluctuation gets in the way. Then such weapons will be illegal for most people to possess.
As for home-cast heavy lead in handloads, common knowledge holds that hard-cast, heavy bullets are not nearly as effective at causing the monstrous cavitation profiles of fancy manufactured loads.
The issue of cartridges being too hot for defense is ridiculous and irrelevant, unless innocent bystanders in the background are hit by loads that over-penetrate. Then the issue would be relevant.
