I have competed with, and hunted with, open sighted rifles and pistols for many years. I grew up with a Remington 33 .22, with a front bead sight. I always struggled with accuracy with it. Then I discovered the "squared up" notch and post. My accuracy escalated. IME, the notch and post is the most accurate of all open sight styles. The front sight and the rear need to be black(ened, if possible), but the front is the most important of the two. I black mine, before using, with a splinter of fat lighter pine, alight and smoking. The soot blackens the sights and there will be no light reflection, which will cause inaccuracy. If the prevailing light comes from the side your shots will move towards the light source. It changes the way the front sight appears, and causes aiming inaccuracy. Blackening changes that.
I despise a bead front rifle sight, with it's accompanying U shaped rear notch.
