Whatever scoop measure you use for the shot (7/8oz,,1 oz,,ect),,use that same scoop measure for the BP.
It's a volume for volume load and is a very good starting load for shot guns wether cartridge or muzzle loader.
One dram is 27.something grains.
Mr Internet will undoubtedly get you the precise answer,,27.3gr sounds about right.
Then you can weigh out your volume of powder the scoop holds in grains and convert drams,,if that means anything to you.
It's still one scoop of powder under one scoop of shot, with a card and a fiber wad(s) inbetween. An overshot wad depending on the loading.
Have fun..
