I've been looking for years for shotgun shell holder for my 12 gauge hammer coach gun. I've got the six round hard mount on my Winchester riot gun but haven't been able to find anything, other than the chincy nylon ones, for a double. Those slip all over the place and stretch out. I saw one made of leather years ago. It mounted around the butt stock, almost like a recoil pad, and was laced on under the stock to hold it on. It was a real nice piece of kit, holding 4 or 5 rounds as I recall. As anyone ever seen one of these or know where to get one?
