While hunting you really have to get your accessories straight. I tightly rolled some newspaper around a 10 gauge shell then taped them to make some home made speed loaders, which I just carry around similar to shotgun shells. There I put the shot and all the wads I'm going to use then sealing them in with a wad of newspaper that I use as an overshot wad. I like the Irish head on my powder/shot pouch as it seems to me that the English head is made for one position only and that's standing up probably designed for the English style of shooting at the "pegs". The Irish head is alot more adaptable as you can load standing, sitting, or in any position.
One thing concerning cost though is the time it takes to load a muzzleloader as opposed to a breech loader. You can go through a whole lot more shells slipping them into a chamber then you can pouring powder/shot and pushing those wads down the tubes. Plus you have to take your time and concentrate while loading a muzzleloader as you never want to double charge a barrel, something you would be hard pressed to do with a breechloader.
All the best
