Steelhead that's pretty good! I believe you managed to squeeze in at least 3 logical fallacy's into one short reply, from the appeal to authority to an ad hominem response. So back to the question I posed If we take Kilkitrik's pictures on page 2 which he was so kind to post if a mono bullet fails to expand is it considered a failure? I would consider those to depict 2 perfect results and 3 results that were at least as much of a failure as the OP's cup and core. The interesting thing is if all 5 bullets were recovered from game I suspect all resulted in dead animals just as the OP's slug did.
