I've seen plenty of DRT elk double lunged, though usually with a frangible bullet I wouldn't attempt to break a shoulder with.
I don't know any of them fancy anatomical terms that Anus is using, but do know a DRT doesn't always require a CNS hit, or at least what we all think of as a CNS hit like the brain, neck or high shoulder.
I read some study somewhere that when a bullet strikes the chest at the top of the heart beat, it causes blood vessels all over to explode and the animal instantly drops...Maybe that's why some double lung hits result in DRT and the other 3/4 or more go 30-50 or so yards before crashing...I dunno.
As far as the OPs question, I try to avoid so much damage to the shoulders, but that's about the only reason I tend to avoid them. That gritty, nasty bone marrow and bloodshotness (if not using a TSX or the like) straight up sucks ass to clean up.
