Craig44, I agree but does that mean only one bullet will work on every thing & others will fail, even on the smaller big game? I'm not defending Hornady, I don't use them either but an awful lot of people have taken lots of game with them with great success.
Some bullets need to expand quicker rather than later depending on the animal. One such animal is a Mountain Goat. I've skinned a fair amount of them for a Taxidermist friend & they are built deep but somewhat narrow for their size. I guess that's so they can navigate around cliffs & ledges where they live.
Anyway, on them you want a bullet that expands fairly fast & works it's magic quickly because as I mentioned they are deep up & down but not real thick.
Switching to something thick & compact like a big feral hog requires a different structured bullet that holds together longer & damages that animal all the way through like the bullets you guys mention or a good, heavy cast bullet. Hope this makes sense.
