This bullet definitely lived up to it's name. Like the Holy Hand Grenade of Antioch. I just couldn't stop taking pics of this one. The deepest recovered fragment only weighed 22.5 gr and measured 0.616" x 0.307" x 0.110" but that fragment plus all the strained fragments (45.6 gr) only adds up to 68.1 gr, leaving 87.9 gr unaccounted for. If you look closely, you can see the mark where a fragment left the block at around the 13" mark, just before the last fragment that is in the block. I believe this to be the core, which should weigh in the neighborhood of 87 gr. Hopefully I can test again to confirm this.
