Ok be4 anyone starts hollering

I just want to know how far is the farthest you have ever seen a trophy buck get after being shot in the heart and lungs??? The reason I ask is because yesterday when we were hunting a friend of mine shot a very nice 160" buck and we tracked him with a very good blood trail, never lost good blood one time. Well another guy saw this buck who is also hunting with us and shot at him with a shotgun from somewhere close to 200 yards away and the buck fell. Well we tracked this buck right to where this other guy shot at him and there was no blood after that. We had tracked him about a 1/2 a mile be4 the blood trail ended. There was only one hole in this deer so unless he had a really bad bloody nose do you think it would be possible for a fatally wounded buck to make it a 1/2 a mile. You're input on this would be greatly appreciated.
