I think producing a clean an undamaged carcass is right up there as a priority alongside a clean kill.
I hear what you're saying but my main focus is shooting deer in the most ethical way possible and use which ever shot presents itself best as I deemed fit.
I'm not in the least bit concerned of loosing a shoulder if the shoulder is the only shot presentable.
Thousands of perfectly clean and undamaged chest shot deer have been entering and will continue to enter the food chain every year.
To me, it doesn't show much respect for your quarry to kill it in a way that results in a significant portion of it going in the bin.
I agree, but alas things can and do go wrong. Your three examples look to be a great reminder of this. The damage on the second animal is not the norm, and shouldn't be regarded as such.
I wouldn't go so far to call the stalker "unethical" because of meat damage, but they do need some educating.
Hindsight is a wonderful thing, what seems a perfect shot doesn't get divulged until you start skinning the beast. Even then it's a long step away from just putting in the bin and discarding completely.
So, whatever your chosen shot placement, minimising waste should be a consideration from an ethical standpoint, not just economics.
Again, I hear what you're saying but minimizing waste shouldn't be the deciding factor in choosing which shot you take IMO.
I feel there are more underlying factors that contribute to minimizing waste than just shot placement itself and of course presenting a clean and undamaged carcass doesn't start or end with the shot.
Not every deer shot will be done so for monetary gain, and not every deer shot by members on here go to the game dealer.
From an ethical standpoint, the majority of us will salvage absolutely everything on a deer before some bits we cant do anything with are given to the dog.
Again, I understand from you're perspective you want as much financial yield as possible from your park deer.
