testing, especially not bare gelatin. 10% jello is intended to reproduce the effect of HOG MUSCLE. The chest organs, with the exception of the heart, aren't even CLOSE to being as resistant and elastic as is hog muscle. The lungs are nothing but Air sacks. Both the liver and the spleen are EASY to rupture with a bare handed strike. You get LOTS more penetration in the chest than you get in gel, and LOTS less expansion in animals than in gel, too. 230 gr jhp's, from a commander barrel, almost NEVER expand in animals, if they aint plus P. They rarely do from 5" barrels, either. They will shoot thru a BIG dog, LENGTHWISE, like in 20+" of penetration. That's TWICE too much penetration.
