My frame of reference is a smooth GM 20 gauge (.620") barrel with rifle sights. On the RB side it's sure lots easier for me to put the balls where I want them out to around 75 yards, compared to a fowler with only a front sight. Meanwhile it digests a lot more shot loads than RB. I find the oversize rear sight a problem for wing shooting, blocking out way too much of my view. Dandy for sitting game with shot though. Easy fix. If I'm wing shooting I just take off the rear sight. Always carry the tools to do just that on days when a hare shoot turns into a ptarmigan shoot. Truly don't need the rear sight for hare shooting with shot, but it's so little a problem I tend to leave the sight on until and unless I start jumping ptarmigan. Truth be known, since I seldom shoot it with RB, the sight would serve better use in a drawer back home.
