Here is where we disagree! Never do I try to fire while anticipating sight picture intersecting the target! Main reason is trigger jerk which pulls you back off target. I was taught and use the following method for OH target shooting: Bring the rifle up while getting sight picture at the point of aim, stopping on target. I do not go upward past the target and back down for two reasons. 1.Muscles are steadier with a firm load(going up) and then to a lighter load, (slowing and stopping) versus the reverse muscle use. 2. When you come up past, naturally you have come back down and now the target is covered by the barrel. Now, when I settle into my wobble (we all have em) the trigger is being squeezed. This is also a timing issue. We all can go through the sequence of the aforementioned in a certain time zone. Too fast and you will not be ready/steady. Too long on the time and you will get tired and gain wobble.
Dry firing is one of the best ways to keep in practice.
