I think a head shot or even a double lung shot would do minor damage to the meat. The head or the rib cage and lungs offer very little resistance to such a heavy and toughly constructed bullet.
Consider this: a 750gr bullet has about 12000fpe at 2700fps. Now if passing through the rib cage and lungs decelerates the bullet to say 2400fps, it would still be carrying about 9000fpe. Which means it delivered the difference of 3000 fpe to the deer while making a half inch hole. Now consider that a 300winmag pushing a 150gr bullet at 2900fps also has about 3000fpe... and the softer bullet will expand and make a hole about half an inch. With good shot placement, the two cartridges aren’t that far off in what they’re capable of delivering to the deer.
Now that said, I’m not endorsing the cartridge choice. If you pull your shot and it goes through the shoulder or back through the hind quarters, there’s going to be a lot more deceleration for that bullet, and a lot more energy will be dumped into the meat, leaving very little for Sunday dinner methinks. As has been said on here a million times, shot placement is EVERYTHING. And it becomes extra important when shooting too small a caliber, AND too big a caliber.
That’s my $0.02 anyway.
