Down in the swamps eh? An older Leupold 4x or Weaver K4 would probably do great then. I like fewer moving parts and had great luck with both of those. If you are hunting in tight cover, I don't think the SWFA SS reticles are the best bet. I'd go either Leupold 4x or 6x with duplex, or the Weaver K4.
To answer the where are the SWFA made, believe they are Japanese made. Have several and they work great in the wide open west. What rifle are you scoping?
