Define the difference between aiming and pointing.
Your head is the rear sight (specifically your eye)
When aiming people tend to sight down the top surface of the barrel as if it had a rear sight, taking a really fine bead.
this will make you actually look up at the sight causing you to shoot low.
Pointing is where, instead of aiming.....one focuses on a consistent hold of the rifle and "points" the front sight at the target...
this allows your head to be oriented higher....thus raising you ball on target.
It takes some getting use to.....this is why many people install rear sights on smoothbores IMO.
