Yep, a few years back I shot a whitetail with a 270, 150 grain Sierre Game King Premium Federal. It was a clean shot but the deer still ran at lest 300 yards in an open field, when dressing it there was adequate damage to the heart and lungs but we found the copper casing in the skin at the small exit would and no lead and it looked like it mushroomed funny to one side.
I have only had one deer run further then 300 yards after being shot, it was a badly judged quartering shot at 175+ yards Now days I wouldnt take that shot, but then it was my very first deer I have ever shot at, i managed to track and recover it. Most of my deer kills have either been close range neck shots or lung shots at further range. Neck shots they dropped like a rock, the furthest I had a deer run with a lung shot was around 100 yards or so, the last deer i shot before I left missouri I put a 150 grain core lokt out of my 308 clean through a nice bucks heart at about 20-25 yards it took off running made it about 15 yards then did a nose dive into the ground and flip over rear end over head and flopped over on its side. when I field dressed it there was nothing left of its heart where the heart should have been it looked liked can of chunky tomatoe soup exploded inside its chest its lungs were pretty trashed too. If a deer had adequate damage to its lungs and heart it wouldn't have run 300 yards.
