One disappointment I have with my lubricated bullets is that I've never been able to get my hands on any rendered bear lard. Any bear who ever tried to eat me was already too skinny for lard rendering. Animal fats in bullet lube may be obsolete technology, but there's no reason a little of it wouldn't work in one of my formulas for low velocity pistol and rifle bullets.
Imagine this scenario: the cute detective couple, the obligatory hot woman and model perfect gym rat young man view the scene of devastation, their only clue that whoever did this thing was very fast and very accurate.
The cute little girl, the camera closing in to the screenshot, says to the camera, more in rhetorical fashion than in real expectation of an answer, "What kind of man could, would do this thing?"
The nerdy little lab technician type, always obligatory in detective screenplays, looks up, sniffs, and announces, "Burnt bear lard. What we're looking for is an old school bullet caster."
The male model lead detective muses, "Hmmm, I had a strange uncle who was a handloader. Those types have their reasons. We may not be looking at a crime scene. It may be something else. Our suspect is very unlikely to have a criminal record."
