As English's excellent post describes calibrated gelatin doesn't replicate living human flesh or tissue. It's an approximation of the consistency of soft human tissue that allows the medium to test a narrow window of data. With that in mind I'd hardly say those who make gel "don't care".
Bullet Test Tube makes no claims to replicating living human flesh or tissue but does state that their formula is consistent to the degree that a calculation can be made to compare with a bullet's penetration of gel.
I see no logic in accepting one artificial but consistent test medium while rejecting another artificial, consistent test medium.
