The Bullet Test Tube might be useful for comparing bullets, but like water it won't correlate to tissue.....
Roy, OIL???? grin......
I don't beleive that the point of these test is to corrolate to animal tissue and bone. I believe that these test were to determine if the HAT bullets will mushroom at all. In goodgroopers test he compared the HAt's to other bullets of known game performance and they mushroomed and the Hat bullets did not and in that reguard the tests are realivant IMHO. No the test will not give an accurate estimate of wound channel depth or diameter in actual animals but, that was not the intent of the test to begin with IMHO.
