Yeah, the one I shot that it happened on, died, and we found it, but it ran for 1/2 a **** mile... At that point all SST's went stuffed into the range bag, and I went looking for something new to dial in before the next weekend. Just happened to be the 160 Barnes Triple-Shocks. Never had one run much from those. Also had one get whipped so hard she flopped over on her opposite side in the air and landed legs facing away from me.
Sometimes you hit them perfect...Sometimes they run. It's just the nature of the game. Just like that first deer I shot this year with the Bergers...Perfect shot right through the heart and both lungs (quartering away about 30 degrees from me)...Ran about 30 yards. Second deer I shot, flopped and never took a step. Can't ask for much more from your bullets and gun, as long as you do your part on shot placement.
