2 years ago, fellow called me and the president of our club, he had just shot an 8 pt in the neck with his 30-06 and been looking for it for an hour could not find it. We went to the club the next 2 days and looked a couple of hours each day, finally found the rest of the deer where the coyote's had not eaten it. Neck intact no hole in it, probably hit him too far back but could not tell that, just no hole or damage to the neck. These anecdotal stories are great fun but do not prove that the 9mm is not equal to the 45ACP. In my desk drawer I have 40 Underwood 147 grain hard cast cartridges that I load in my P365 when I carry it hunting, different mission, different bullets.
