Not trying to be argumentative, but I'm still not sure what you're getting at. Just because you break their shoulder doesn't mean they they're not going to be able to run.
My dad used my 270 wsm with a 130 grain Ballistic tip and shot a large mule deer at 225 yds. in the shoulder and the bullet blew up on the near shoulder and the deer ran off. The shoulder was broke but the deer still ran about 500 yds. before laying down and we had to stalk up on it finish it off. I'll never use a ballistic tip again because of this. That's what made me switch to Accubonds.
Now, here is the weird thing. Every animal I've shot with the 270 wsm and the 140 grain Accubond has dropped in their tracks, all pass throughs. Hardly any of the animals that I've shot with the 300 WM and the 180 grain accubond have dropped in their tracks. Some will stand for a few seconds before falling over and some will walk up to 50 yds before falling over. I've shot them behind the shoulder, through both shoulders and through one shoulder and pretty much all have died in 50 yds or less. I've recovered three Accubonds from my 300 WM. One from a big cow elk, broke far shoulder and she ran about 25 yds and face planted. Two from mule deer. One was running away up a hill and below me at 250 yds. I hit it between the shoulder blades and broke far shoulder. It dropped in midstride. The other was trotting at about 80 yds quartering away. Hit behind near shoulder and broke far shoulder. Deer slowed and walked 10 yds and layed down where I shot it through the neck. All three recovered bullets were perfect mushrooms and retained a little over 60% of weight. The lungs and insides were all mush in all three. Not sure what else to expect the bullet to do.
A few of the animals I've shot that were pass throughs showed a fairly small entrance and a fairly small exit, but everything in between was destroyed. Again, none went farther than 50 yds.
I just started using Bergers in a few of my rifles but don't have enough kills to know for sure how they perform on game. From all the reports here, I think they probably work great.
Bottom line is, if you are doubting the Accubonds, you should try something else. Inevitably, you will have a bad experience and blame the bullet. Find a bullet you like and go forth and kill things.
