Be sure and measure it BY VOLUME to start. When people say "I used 100 gr of BH 209", 99% of the time they are talking about a volume of 100 gr, not a weighed charge. Different powders weigh different weights for a given volume, so we use volume to compare different powders.
As stated in the video, you will need a flask, a powder measuring device, and some type of containers to take a premeasured amount of powder into the field. I personally like this type of powder measure, because it comes with its own top leveling device which doubles as a small funnel to make it easier to pour down your barrel and not spill any.:

I use the brass powder flask like in the video. And the "lanes powder tubes" are great or you can get ones like this:

They are pricey, but keeps your powder, bullet, and primer all in one package.
