I appreciate the insight. After setting it up on the gun and evaluating the eye relief, I believe that if I scope a shotgun, I'm going to go with one designed for shotguns. It's been a while since I've been hit between the eyes, and while I wouldn't be suprised if it happens again before I give up hunting, I don't want it to be with a 3.5" magnum. And this setup looks like it would do the trick. My son's all grown up and moved off with a bunch of our guns, so I've been thinking about a new .22. That old Redfield would be perfect...
