Strong barriers.

It literally took a supercharged Nora launching an entire team with all her strength for the barrier to break, and even then, it stopped them for a while before breaking.

So she has no reason to use weaker rounds. And "dismembering her oponent with simple rounds" is not supposed to be a problem due to this thing called Aura preventing such things.
