That is odd. I can't say I have ever seen a 25 Horn HP from my .17 Rem do anything but put a small hole in a critter, then blow up inside and not exit. I can't think of any neck shot coyotes I have taken with that bullet/round but I am sure I have done it. The only "bad" thing I have seen them do is take the front leg off of a red fox I shot a bit low one time. This includes a lot of thin skinned critters like rabbits, though it'll tear a prairie dog up like most anything will.
I have a few thousand of them left, but they're all manufactured from within the last few years.
