[/quote]I have limited experience with the Grendel but so far it seems to kill far better than you think it does based on math. I know arithmetic doesn't lie but some combinations of bullet, case, and powder seem to work better than the math says they will. I have a combination of .277 Win. power point loaded in a .270W at 2750 fps that works on game way better than a 7mm RM I used to use.
It is really more of a bullet & velocity issue. Some of the quickest killing bullets on thin-skinned game like deer are those that open up violently upon impact. Cheap cup & core bullets driven fast.
The 90gr bullet can achieve plenty velocity out of the Grendel to be and excellent 200 yd deer killer, but it doesn't have the high BC that the sniper wannabes desire.
