For me, I would want my rifle set up with a set of Recknagle or similar swing mounts and regulated for scope use. I sold my first one because I couldn't mount a scope on it. I've only had two doubles and a couple of drillings. There is a romance about shooting with open sighted doubles and they do handle a lot nicer, but to be honest it's hard for me to shoot well with open sights. I shoot my double a good bit, and I still wouldn't be comfortable shooting beyond about fifty yards with the open sights. I wouldn't hesitate to shoot to 150 with the scope. One of the things not often considered is the varying light conditions when shooting in the field. I've noticed that I shoot better in good light with open sights. I shoot somewhat less well when the light is not just right. That's not a problem at the range, on safari, it could be a problem. I believe it is my responsibility to put the shots exactly where they need to be. I can do that with the my double, but I can do it further and more consistently in all kinds of light conditions with the scope on it.
