i wonder how many crime scene investigators would know a "handload" from a commercial round to begin with. the outward appearance of one can often be identical to NIB factory ammo.
i know of one case personally that resulted in an empty revolver, there was no mention of non-commercial origin in the LEO report. any of the recovered bullets would likely have shown same clearly. they were scored down through the jacketing of the bullet base with a triangular file in an "X" shape, and loaded backwards.
the perp had an extensive history of arrests and convictions, many of violent nature ranging about ten years period. the shooter had traffic tickets before. the closely located non-involved witnesses confirmed the shooter's story. the perp had physical superiority. the perp initiated the physical assault, and charged after being told to disengage at gunpoint. at the cost of everything.
LEO's generally refer to encounters like that as "good riddance shootings". likely at volumes that only their co-workers will hear. i can't say with any degree of authority as to whether the homegrown ammo was ignored or missed. none of the heavy 265 grain slugs stayed in target.
in a shooting of questionable provocation, it could be a problem the prosecutor will use to raise doubts about whether the shooter was secretly "wanting" or "planning" to get into a situation with a similar result.
the point being made above about the evidence of what actually caused the shooting outweighing the bullet construction is generally, and at very least, ideally true.
i don't have reliability issues with factory ammo. i also think any load a sane person can make at home will be available as an equal on store shelf. maybe in a specialty format, maybe shipped from great distance, maybe at a cost premium, but obtainable.
why add to your liabilities if you are forced into a shooting? this is the conclusion of most police department lawyers.
