I have found the 20x SS scopes to be unusable, but that probably has more to do with my vision than glass quality. It seems to me the 16x and 20x scopes aren't very popular though, at least among this crowd. I swapped a 20x for a 10x, and I have no difficulty at all using that one. I think the image is pretty good, actually, and is very usable.
It's not just you, the 20x's are duds. I picked up a used one once just for doing load development and at 300 yrds the glass just wasn't clear enough to see the targets well. Sold it and replaced it with a 12x which was much better, .
