Lord I hope not. I don't have any use for a 12X scope. Don't own a rifle that a 12X scope would be appropriate for. Such a rifle is not a hunting rifle anyway, so I have no use for one.

Re-reading this thread, I realized that Mac got it right. The reason is entirely misconception. Most of us who hunt with medium and small bore doubles, as well as large bores, would sooner do without the large bores. Very few will ever really understand the double rifle, and that's a good thing. More for those of us who do.
