I don't take much gear at all with me with my smooth bore. I make speed loads from paper tubes that hold powder and shot, which I then use the paper for wadding. I use my gun strictly for hunting so I want to be fast and light with it. Aside from the speed loads I just bring a priming flask, extra flint, vent pick, pan brush, and a small screw driver for the jaws of the cock. I carry it all in the same pocket of my hunting vest.
You can carry a seperate shot pouch or snake like some guys do, but for hunting purposes where a quick reload is required, I find that stuff to be a detriment.
I load 70 grains 2fg powder, a couple crumpled up wads of the paper, then 80 grains shot, with a wad of the paper to hold it all together, tamped pretty good to get it all tight in the breech. I've never felt the need to use those fiber wads or cards whatever. The old guys didn't use them and they killed game.
