I have a question about longrange kills on big game sized animals. What causes these animals to drop in there tracks at these long distances? Is it the shot placement? Or is it that the bullet is hitting them with a lower KE and the bullet expends all of its energy into the animal and none is wasted? Just watched new show Long range pursuits and shot a elk at 900+ yards with a 7mm and was dead in its tracks, but you see some closer shots and animal runs off before expiring.
