I have several guns I use for hunting deer and most have just a scope. I do have one that I use in the deep dark woods like northern Maine which has just a Williams peep sight. For the most part I don't have a problem with hunting with a scope except during heavy snow. I haveflip upcaps that I put on the main rifle I use to help but it is a bit difficult to make those real fast shots that sometimes come when you are tracking in the snow. I put see through mounts on my slug gun which I use late season when I go to the mid west for a hunt. If the scope gets snow covered or foggy then I justuse the iron sights. I do feel that long range accuracy suffers from using the scopes set so high using see through mounts. One of my ML guns has detachable scope mounts. I do feel that even though it is close to same point of impact it does change the accuracy a little after removing and replacing the scope.
