What are some of the benefits of the classic double compared to an Over / Under express rifle? The express seems to be popular here in Europe in mid range calibers. I've seen many of them in metric calibers up to 9.3mm. I watch the online auctions sites pretty closely and the money for a SxS double is definitely higher than an express rifle. I've never shot an express rifle, so my knowledge is pretty limited. I have guided a couple of men who did. They certainly seemed to like them and they handled well. Someone out there surely has guided a client who used one or even owns one themselves. What are your thoughts?
