So to blame the bullet right off the bat is just not the correct thing to do. A properly placed bullet will kill-period. Even with ZERO expansion it will kill. Maybe not as fast or efficient, but it will KILL.
What HEAD said.
Two or three years ago i started rushing my shots. After several long tracking jobs and long dragging jobs it was back to careful shot placement. It's a bad thing those animals suffered.
Yes, shot placement is important, but not every shot can be properly placed, in a hunting situation.
If you can't put the bullet in the right place then don't take the shot. No ones bullet is going to turn a gut shot into a bang flop.
