Weeelllll for the most part this is true and valid advice....Up till you are trying to go really really fast like my son and I do in competition.Are you familiar with the concept of "riding the reset"? Frankly, it's the biggest reason for large and inconsistent group sizes. Squeeze the trigger, do not let up when the gun fires, feel the tactile resetting of the trigger as you slowly and under control, let pressure off the trigger. STOP at this point and then regain your sight picture and squeeze again for your next shot. Your follow-up shots will be more consistent and exponentially faster once you master it. Feeling the reset and understanding the mechanisms at play is easily done during dry fire.
I used to be a competitive shooter and still do alright at the range. My targets where the rounds don't end up in the 10 ring are usually because I tightened my grip and shot over to the right at about the 4 o'clock position. You seem to be an asshole that is full of yourself. Add something useful to the discussion. By the way, dry-firing and calling your shot is a very productive exercise.
Also teaches you how to fix your gun during a fire fight. Well done.Something I was taught by one of our instructors for live fire is to load dummy rounds in the magazine with live rounds, 2-3 at random. This sure helps me break the anticipation habit that seems to creep in on me.
