Usually hunters would use expanding bullets for the better effect. The bullets tend to fragment and some of the fragments spray from the exit wound. In most cases that is not a problem when hunting. A hunting magazine conducted a test and found that the fragments may cover an angle of about 45° from the original direction of the shot. When tracking down a wounded animal with the help of a dog (the dog must be used around here), the dog may be in that cone and get hit. This is why for this situation usually FMJ is used. It does not pose a thread to such a big area. That does not mean that there is no risk of unintended hits though. The probable deflection was found to be up to 10°.
