I don't think I can improve either on what sabotloader said. My grandpa, back with open sights were the only game in town, said to bring the sight straigt up the front leg and pull the trigger when you get to the body. Your "follow through" puts the bullet right in the "boiler room". With scopes, we can obviously do more precise aiming. I use to put the crosshairs behind the rear crease of the shoulder. However, I now hold it further forward, directly above the point of the elbow and 1/2 way up the body. No matter what, they will not go far if you get the bullet there.
