Steve,
Thanks.
I don't know how useful it is out in the field. I have tested it with a combo of ball and shot and both sides dispense easily when you close the other with your fingers. In that regard, dispensing lead from it isn't as straightforward and effortless as with a single compartment bag, but that's really not the point of it I guess. What combos of ball/shot or shot/shot you carry in it would only be limited by your needs and the diameter of the spout.
