Honestly, I do not know sir.
In shooting sports, there are prizes other than winning the trophy. In a real shooting fight, the second prize could be death. Many treat guns as toys, hence, enjoy them as part of a sports interest, nothing more than a racket in tennis or a cue stick in billiards. There is nothing wrong with that I suppose. Each is entitled to his personal enjoyment and pleasures.
But guns... are implements.. tools of death...or at the other extreme, beautiful decorations on a glass cabinet or a wall.
Markmanship, or more technically in the very context of this discussion, proficiency in weapon handling, under stressful situations can never be truly learned in friendly competitions, where participants shoot at a target and/or targets that does not shoot back. Emotions aroused in an actual firefight can never be simulated in a civilian shooting range. Even in a military boot camp training where the trainee knows they are deliberately shot at some thirty inches above their heads feels a tiny sense of comfort.
Proficiency in this perspective would mean, muscle memory, such that the shooter hits the target he is looking at... without consciously aiming, without having to align the sights, whether plain iron or high tech electronics. That may be brought about by constant and diligent training.
You can start by dry firing your weapon, everyday. That way, you can teach your muscles to become very familiar with the feel and weight of your weapon, especially the trigger. The objective is... feel your weapon. And, do not watch too many movies with shooting in them. They are ... just movies.
Sorry, I do not really know.
