I've mentioned it before, but I'll post it again. I hunt quail in rugged terrain and was often unknowingly dropping live shells from my pouch or vest with simple button closures. Velcro closure pockets were clumsy and awkward. I wanted a shell pouch that had a spring closure like some of the empty shell waist mounted net bags and the gunslips from Wild Hare. I didn't find one for years and was going to make one until I ran across exactly what I wanted at the Shot Show a couple years ago.
It's made by Drake Waterfowl and called a "shooter's belt and gun rest". It has not only a strong spring overcenter closure, but also another compartment for wallet/phone, meds, etc, that closes with a spring and a double security large velcro "lock". The shell pouch stays open on its own and closes with the slap of the hand or elbow. I don't hunt quail/chuckar without it anymore.
Cabelas and Basspro both carried it for a while and then dropped it. Must not have been discovered by other upland hunters.
