I am not so sure about that. Certainly have to be able to see well enough to align the sights. I bought a .22 "Free Rifle" which has double apertures sights. Its only purpose, ever, was to plunk one hole on top of the other at 50 meters. I want to try that. I see various World and Olympic scores, using that kind of rifle - 400 points for each of top 5 or 8 shooters. So each hit the 10 ring 40 times in a row. I bought some 50 meter official targets. That 10 ring is about 0.4" diameter. In World competitions, they count the "X" hits to break a tie - X-ring on these targets is less than 0.2" - so smaller than a .22 bullet. So far, as I have learned, they can not see either the 10 ring or the X-ring at 50 meters - they are aligning their sights with the 4.4" black round bull - and notes I have from that level of shooters are constant that you need to see a "ring of white" around the bull to know if you are aligned.
I had a Weaver K3 scope with fine cross hairs and a 3 MOA dot in the centre. I made 4" diameter white targets with a black ring around outside. So I would see a "ring of white" around the dot - was actually surprised how easy to see slightest mis-alignment. The rifle was quite accurate - a 243 Win. I shot many 3 round and 5 round groups in the 5/8" to 3/4" size, at 100 yards off a shooting bench with sand bags, with that 3 power scope and that white bullseye.
