It sounds like you need to get some coaching on shooting iron sights, IMHO. Maybe Dave(Smokin'50) can get together with you at one of the 3 clubs where he shoots in New Jersey, and give you some pointers.
You may not understand that with Any iron sights- handgun or rifle, or smoothbore--- you concentrate on the front sight- not both the rear and front sights, nor on either of them and the game or target. The rear sight should be "fuzzy", and the target should be also. Only the front sight should be clear in your vision( eye).
Yes, you align the front sight in the rear- that is how you reduce vertical and horizontal dispersion-- but you Look THRU the rear sight, Not AT IT. Then, while focusing your eye on that front sight, you align the front sight with the target, or game, and squeeze- not slap-- off the shot.
When using a smoothbore with Shot to Hunt upland game or waterfowl, where shots are at Moving targets, you POINT the front sight at the target, and slap the trigger.
Same gun, Two different ways its fired, depending on whether your are POINTING, or Aiming a target. :thumbsup: :hatsoff: :hatsoff:
I have worked with "natural" shooters just like you many times. They all were very good students, and picked up the differences very quickly, and were very good shooters. Give yourself a break, and find a coach.
Oh, most of my students have NO experience with shooting iron sights- even on a .22 rifle- because scope sights were so inexpensive and " Necessary" when they got into shooting. They simply never had an opportunity to learn how to shoot iron sights. Its very easy to spend an hour or so at a shooting range, with a .22 rifle, using iron sights, to teach these skills to an experienced shooter, and then watch that student use a rifle or shotgun, or handgun and get it right the first time. Most of my students like the exercise where we turn a target backwards on the target stand, and have them "AIM" at the center of the paper. They then use the first hole fired into the blank paper to aim their following 4-9 shots. We then turn the target over, and score the target using the rings and bullseye on the other side. The first time we do this, the scores are so-so. The second time we do this, we see vast improvements.
If the student doesn't have his own .22 rifle, I have a few I make available to my students to use. :hmm: :thumbsup: when teaching shooters who will use MLERS, I always FINISH the training by having them do the same "blank target" exercise with their own MLERs, shooting just 3 shots, at 25 yds, off-hand. They are most proud ( And should be)of that last target when we pack up. :hmm:
