Those bright fiber optics dance in front of my face - I can't use them AT ALL. The best irons for me are a simple U-notch rear with an ivory/white ball up front. But I would be dern lucky to shoot nearly as well as Semisane did with any sort of iron sights. Just can't get things together past 25 yards and I'm shootingbased upondistant memories even at that distance.

That old Zouave seems to like your load combo, Semi, and I think you could do just fine with better sights. The 50 yard group is mostly spread vertically indicating to me that you are climbing up and down on the front site - but not a lot.
