Swiss 2fg & 3fg Volume VS weight

Both, 2fg and 3fg are grain for grain, after volume measuring and putting it on a scale. Because Swiss flows so easily, any bumping, the slightest amount, can throw the volume charge 4+ grains heavier. The 2fg was super silver in color. Most likely the graphite in the powder which makes it flow as smooth as it does.

Okay, I see the 2Fg, where's the 3Fg? Curious if there is a difference in weight between an equal volume of each. Or does Swiss not make a 3Fg? I have no experience with it.

I didn't picture it as I did that test long ago with 3fg Swiss. Both weigh the same from a 70gr volume measure.
