Use an appropriate size target?
Like 12" for buckhorn sights. Maybe 8" for a peep, 12" if you have trouble with 8". Some 12 inch shoot-n-sees are useful to have in your bag.
You need a big enough "blur" to be able to consistently align your sights with it. And do I need to mention that you need to be on a bench, with bags? The target should be a blur, because you are focusing on your front sight only, so that blur needs to be the right size and color, with enough background to make a consistent easily-distinguishable blur.
Now with scopes... 11" divided by magnification for scopes works pretty well at 100 yards, for me and my reticles. Basically, in my scopes, I want to see an 11 MOA circle to aim at. So at 600 yards with a 22X scope, I want 11 times six divided by 22 equals 3". So yeah, I want a 3" dot at 600. On a 4X scope, I'd want a 12" target at 600 yards. Etc. (Truth be told, I prefer an 8 MOA circle inside an 11 MOA circle, but that's not always practical.) I have found that if the aiming points get much larger than this, my group size suffers. Like those 36" circles at Anniston at 600 yards... I hear they have addressed that, but I haven't been back. Hard to shoot a tight group when the circle is pretty much the entire field of the scope. So you end up lowering your magnification, and that tends to hurt group size.
Get further than 600 and mirage may affect the minimum size, but if you shoot that far, you already know that.
And if you have really thick reticle lines, you may need more than 11 MOA to aim at. I have a Leupold 2.5X, with the thick lines, and I need 20" for that guy.
