Shot a buck tonight around 4:00... Thought it was a good shot. Right behind the shoulder at about 20 yards. Buck ran off with my arrow still in him. I tried to trail him until dark but I'm not finding much blood at all. A few drops 50 yards from where I shot him and another drop where he jumped the fence. I felt confident in the shot but the blood and the way there deer acted after has me feeling uneasy. This was my first buck that I had shot with my bow and not exactly sure what to do
