I am very fussy about scopes for my double rifles: I have little or no objections to my using a nice small scope on any of my O/U rifles, but prefer not to use scopes on my SXS rifles; stick with iron sights on them. However, if hunting conditions dictate a scope is needed, I infrequently use them even on my SXS rifles. But, whatever double rifle I scope, I NEVER use a variable scope; variable scopes are simply not needed; are only a feature to increase sales to non hunters or hunters with little experience. For one thing, variable scopes are too large in physical size, and for another, when you see game, you are not going to have time to be fooling around resetting scope power (the only time variable scopes may be acceptable, is for varmint hunting, in my experience). Most importantly of all, I prefer a single power, low power, scope of only 2 or 3 power, more than suitable for double rifles, and one that is the smallest scope I can find, with smallness being extremely important.
