The
9mm Ammo Quest series of videos (which includes bare gelatin and 'denim' testing) is some of the the best and most comprehensive comparative testing readily available to the general public.

Also, note that the FBI Penetration Test criteria (post #20) does
not include ballistic gelatin damage caused by 'cavitation'... the criteria includes simply 'penetration depth'.
'Cavitation' and the damage associated therewith has been studied for decades by the military and law enforcement and has been debunked for service/self-defense cartridges.
Contrary to 'Internet wisdom', the 'cavitation' demonstrated by ballistic gelatin is a characteristic of the gelatin and NOT a characteristic of the human body.
The first 'hint' indicating as such is the calibration depth of the BB... which is 2.95" to 3.74" (with a 0.177” steel BB @ 590 +/- 15 fps).
A 0.177" steel BB @ 600 fps simply doesn't penetrate the human body (or a pork loin
) to near that depth.
The FBI considers the 'dependable' damage caused by the bullet to be the 'crush' cavity produced by the bullet's diameter... no more... no less.
Hence...
Enjoy the videos.
