Practice ammo doesn't need the level of QC that defense ammo IMO requires.
Your comments indicate that you don't see a difference; we'll agree to disagree.
All ammo types require safe loading practices, but defense ammo should be held (and tested periodically) to a higher standard. You don't think factories do testing on every lot and likely gelatin testing on defense ammo? By tracking ammo (and components) by lot numbers, I could remove only the suspect ammo if something wasn't acceptable during testing. Ammo manufacturers do the same thing on a larger scale. If you blew up a pistol with factory ammo, I am certain they'll want the lot number.
Muzzle flash and temperature sensitivity are concerns considering the possible need for low light shooting. For practice/match use, mixed brass is fine, but not for defense. The same for a meticulously perfectly seated primer. I've never had a round fail to ignite first strike, but if it happened in a match or practice, nobody gets hurt; not so in a fight. The same for burrs in a case rim; OK for practice, not for the street. I use a tight case gage for match ammo; anything that fails becomes practice ammo (where it will likely work fine, but why risk using it at the end of a match with a dirty chamber). Oops, that'd be a middle tier of ammo quality for me.
In reality, any of my reloaded ammo is probably good enough to grab in an emergency, but I prefer to stack the statistical odds in my favor. Factory ammo QC helps with that. I also shoot a few out of each new box of factory ammo as a final function check.
