"The 11-pointer"
Congrats on that big buck.
Your post brings this thread full circle, sort of back to the beginning. It confirms the idea of needing to see the animal to really determine something of the terminal ballistics and forensic evidence. It also shows most any modern bullet will lay a whitetail low. And, it comes back to the lament of "no blood."
Thirty yards is not very far at "whitetail-speed" and the chest cavity has not had time to fill and leak; but it illustrates to me, once again, how frustrating they can be to find if they do not leave some red where standing when shot.
Once upon a time I seemed to get pretty consistent and immediate blood splatter with the shot you described; but I was shooting an '06. There is not much difference between 30 caliber and 7mm in hand, but I expect super slow-mo inside an animal might tell a different story. At any rate, bullets are different now days, with a premium on controlled expansion.
A 7mm and 30 yards and no blood might not be the corelokt's fault, or at least a not a flaw.
You began and ended a perfect thread. I still think corelokt's are workhorses ... not racehorses, show-horses, walkers or pacers. They will not shoot target holes with the best out there, and especially not fine tuned rifle-mated reloads. And, for all I know, there may be some economic voo doo and short-cutting in their production, but I sorta doubt it.
I am not into conspiracy theories much, not even my own.
But, they will kill 11-pointers.
Congrats on that buck.
