Looks like text book performance to me.
If your textbook is old enough. Perfect performance, 1920-1980 style.
No exit wound when using a 280 on a mere deer? Sorry, not good enough. Not even sort of.
I disagree. I have 3-4 recovered bullets from deer. 2 from raking shots that were found in the hide after passing through the offside shoulder. Both from a .30-06 165gr/core lokt. One last year from a 140gr Federal Fusion out of a .280 Rem that that hit the on side shoulder and traveld about 18" up the spine and I recovered it in the hide on the neck on the oposite side. All perfect mushrooms. I have shot about 25 other deer with no recovered bullets that produced the same results.
The other one is a core from a core lokt that I recovered in the ham of a doe on a facing shot from a 180gr core lokt in a .308 Win.
All deer were dead and all but the doe dropped on the spot.
