I never thought about it from strictly a hunting point of view, but having a button on a hunting bag makes sense. When I go to shoots, I shoot out of my bag and not a shooting box, because I try to keep it simple. I have 5 guns, 2 45's, a trade gun, a32, and a 25. I use one bag for my 45's, because I use the same for both guns except for a primer and capper, that way I don't forget stuff. I use a bag for my trade gun, and another bag for my two small caliber guns, because everything is the same except for ball size. My bags are always ready to go, just have to grab powder horn, gun, and bag and I can shoot. If I go to a weekend shoot, I bring a shooting box with extra shooting supplies. I digress.
