I can shoot al my arrows in a pie plate at 40 yards my guts tell me I can make that shot
but my brain tell me that there no easy shot in the wild.
So I stay to the 20 yards distance even if I get angry at myself to have left a perfect broadside shot at 30 yards.Dont forget that there might be a twig in the arrow's path,deer might move at the same time of the shot.In a milsecond wind can turn around and the deer react to a drift of different odor etc.Keep it to 20yards and you won't have to blame either your brain or your guts.
Happy hunting
