Couldn't tell you. I know the range and if I feel very good about the shot I shot. Generally no more than 40 yards. It really depends on the animals state. Chuck Adams got flamed for shooting a leopard in Africa at 60 yards. However, the leopard was bedded and he had all the time in the world to put a good shot on that animal. I don't think you can say anyone that shots over 50 yards is unethical. Every situation is different and every persons abilities are different.
