My habit is to take a couple of saved plastic grocery store bags with me for trash .. hulls, mine & any others I might pickup along the way, pop cans [I stomp them flat] or whatever else I find that is objectionable in the field. The plastic bags weigh nothing to carry in and I try to practice a rule of bringing more out than I brought in. Unfortunately, most of the time it is possible to do that. Not always, but often enough. Doing it sets a positive example for others and is almost never unappreciated by the land owner.
BTW, I find hulls from the field are not usually suitable for reloading as they go in the bag with the birds initially if its dove or quail and get feathers and blood on them and if they are picked up off the ground there is sand and dirt involved. If it is waterfowl being hunted then the floor of the blind or boat bottom is usually wet &/or muddy and the dogs are shaking water over everything too even if it is not raining on that particular hunt. For those reasons my reloading hulls come from the gun club or my own target shooting activities.
