So.....you figure your .338 would have destroyed the heart even more? Animals drop and die from vital organs and bone structure being destroyed, not by foot pounds of energy. It looks to me like the 7-08 did its job with aplomb. Even a .50 BMG wouldn't have killed that deer any faster unless it managed to mangle the heart and vitals even more than what you see in the pic.
A neck shot is an iffy proposition. If the major circulatory system or spine aren't hit, a shot in the neck will not cause immediate death.
Think borscht...When you square the heart. Nothing that size remains.
Oddly enough its super easy on the meat....Much more so than a 30-06.
In my experience most deer lung shot with a 338Win bounce 10-20 yards then tip over...I would hardly call the deer kills the 338Win makes spectacular...Just not enough there to cause violent expansion with those (made for huge game) bullets. Shoot a moose and it is a very different story.
I shot a 60 pound Island deer with my 340Wby with a hyper velocity 160X.... It made it 60 yards with nothing inside (just had to trim the wind pipe).
Not normal, but it can happen.
