Gentlemen, can you recommend a good "dual purpose" .44 mag self defense/thin skinned predator round (no Specials please)?

Looking to expand the capabilities of my .44 mag Mountain Gun. Will be on quite a few hikes/camping trips all over in the next year, and while I have already covered my bear rounds and I would love a hint towards a solid two legged to thin skinned four legged predators.

If over penetration occurs, I'd prefer it to be fully mushroomed or fragmenting at exit. And while I'm not an energy nut, my gut tells me 700 +/- foot pounds with a rapidly expanding projectile would feel right out of a 4-inch revolver tube. I'm also feeling a thin skinned 180 grainer might be my only choice-but would probably prefer a lighter/faster round if available?

Anyway, I DID try the search b/c I know I'm not the first to ask, but for some reason the function shows no results, even for just "44".
