These fellows are right on the mark. Although I will wager, if you place that bullet in the right place, you will not have to track very far, if at all. I have knocked them off their feet with a round ball, so as they said, deer are hard to judge. The experience comes in the fact that you are giving that hunt a special challenge. You will have one chance (normally) to make your shot good, and there is that slim chance with an inline, that it might not go off.... Good luck hunting, and be safe. Let us know how you did...
