Sort of. Ballistics gel emulate the density of tissue, but it isn’t a perfect emulation. How stretchy parts of the body are and how connective tissue and your skeleton holds things together means that even though there is a wound channel, it isn’t the same as with the gel.
I can’t find a video of it but mythbusters shot a pig carcass balanced on a hook with a .50 BMG, and not only did it not fall off the hook, (dispelling the myth that bullets can knock you back), but it just zipped through IIRC. Granted it was probably a FMJ, but if you look at this video of shooting 2 blocks with a .50 BMG, it shreds it apart.
Also they must be using the same gel as it too has a spark and is clear.
