I have an almost new SWFA 20x in the classifieds. The reason I bought one in the first place was for load development and rifle verification so that I could detect wandering zero and other problems with my Leupolds, but unfortunately it is not compatible with my vision (I think I've developed a severe astigmatism in my right eye after a recent infection, or could be cataract, don't know yet). I just flat can't see through it from one moment to the next. It's weird. My Leupolds give me NO problem whatsoever---as far as image quality goes.
