my only concern about using the quiet series - even the segmented ones if you can find them - would be the high probability of a crawl off. shot placement would be 100% critical for a DRT type situation. since they're just a CB short in a longer case (identical ballistics), the only difference is the fact that they will feed in magazine fed platforms.
in my experience, groundhogs are a lot tougher than a feral cat or crow.
