You will see this tool used by a lot of people at a muzzleloading shotgun shoot, it's marked in ounces of shot but most everyone uses it to measure the powder charge too. A lot of shotgunners refer to their powder charges as "ounces" as measured by a shot dipper, many don't even know the charge they use in grains.
Track of the Wolf also sells fancier dippers and shot flasks.
