It's like this with FFP,
a .025 mil line thickness is okay at 24x, getting harder to see on 16x, and stupid hard to see on 4x. Everything is a compromise right?!
Usually one buys a mid magnification scope/4-16, so they can hopefully use/see the reticle on 4x occasionally, right?!
Now try a .05 mil reticle thickness, not too thick on 24x, fine on 16x, and seeable on 4x. It's twice as thick as .025 mil.
Let's say a dot is .1 mil which is very thick but used quite often these days for holdoff dots at the full mil. At 2000Y that dot obscures 7.2". Is there anybody really missing a 24" plate because of that dot???
Now those huge friggen numbers labeling the mil or moa lines just off the vertical crosshair, THAT is what's obscuring! But people don't mind them which I've never understood.
