http://www.tridentfitness.net Rich Graham demonstrates shooting "holds" and bullet path vs line of sight in this shot. He is shooting through his own personal truck from about 15 yards away, and the target is about another 15 yards on the other side of the truck from the standing position.
Since the truck is inside 25yards the bullet path will still be below the line of sight. Rich shows student here in this demo how to aim using "holds" so he does not shoot the door of his truck.
Lastly this also builds trust in your abilities and understanding of where your bullet will travel and trust in your abilities as a shooter.
In this video Rich is seen shooting a Strike Mark self lifting steel target system.
