Think a dum-dum tank shell could work against real big stuff, like mutated land whales with thick, blubbery skin. Too much flesh for a bullet to penetrate, and super tough, but not in a way that's helped much by armor penetration. Though if regular tank shells don't cut it, specialized flesh-rending rounds probably won't either? And don't think dum-dums scale, though there's probably some way to make an equivalent effect for larger rounds, as impractical as it'd be IRL...
