I assumed the round dots in @YampaValleyMountainMan 's sketch represent a front "Bead" sight, not the target, but he can clarify that. I can't imagine how you could bury the target in the rear sight notch with no visibility of the front sight in position "B". That's what lead me to the conclusion the round dot is a bead.
On squared off sights like you pictured I use your sight picture. On the "V" type sights I like position B with the bead tucked way down low. For me that lessens side to side error by not having to estimate an equal space on each side of the bead.
I want my bead as low as I can get it! I have eye problems now and can no longer shoot well. I would like to remind people that the square sights we see on most rifles today were just about non-existant prefifties. As scopes became the rage gun factories started cheapening up on sights and we started seeing the square sights. These type sights are not conducive to extremely accurate shooting. There is a reason rifles had bead sight or silver or brass blades. People put peep sights on rifles. They are aware that it is needed to wring out all the accuracy a rifle has to offer. It is next to impossible to do it with the cruddy sights they put on rifles now? With that said I have seen some decent targets shot with the square sights but very few.
This type sighting is what I used on aierial and running targets. You don't have time to draw a fine bead plus your target is generally close which allows you a bigger margin to work with.
I’m with ya out to 100 yards with the rock-lock….. much beyond that I using glass - in this case I’ll kick back and look thru the binoculars - mainly because the rifle isn’t up to my accuracy standards for a shot on game much over 100yds.
