When a bullet produces no exit wound (and in fact has no mechanism to produce one unless it fails to expand) that's a failure. Less blood loss, so you get animals going much further, and no blood to track so you're much less likely to figure out where they went.
Berger's "hunting" bullets are designed to fail. That's why no one reputable recommends them for any animal larger than a varmint.
Every single one of your points here is false. Congratulations. And unlike you, I've actually watched Bergers kill critters, along with every other type of bullet you cited. Maybe you should put down F&S and get out and actually get some kills under your belt with the bullets in question, before coming on here and making claims full of nothing but verbal bile.
