Similar to a shot, if the deer haven't seen you, you can usually stop running deer with a short quick yell. They usually won't continue until the have identified what made the noise. They won't run into potential danger, and by yelling you can confuse them. This once again only usually works if the deer haven't already identified you.
That works most of the time . I have done it before with a shotgun but not in several years . I douldn't even consider shooting at a runnig deer with a rifle .
