I've got one of the S&J 12g pouches with the Velcro backed cards and they work great, we'll built piece of gear. I don't think I'd put the Velcro on a wood stock though, a friend has a nice wood stocked O/U and he's got a well made neoprene slip on butt stock shell holder. I'd likely go that way but the S&J pouch is easily worn on your belt and in reach.
