Penetration depths for the string you inquired about were 13.5, 13.5, 14.0, 13.5, 14.5.
Probably because that is an nonsensical question. The bullets were "true spec" to use your verbiage and had a nominal weight of 147 gr when fired. The recovered bullets have a bit of test media embedded in the folded metal "petals" and thus gained a minute bit of weight, as has already been explained to you earlier in the thread. This seems a very simple concept to grasp, yet you are failing to do so. Are you just being willfully obstreperous or are you truly so ignorant that you cannot understand this phenomenon?"How do I know the HST bullet didn't penetrate 13.8" because it was a 148.4 gr bullet?"
