I got bored and measured both Pyrodex RS and FFg Black powder

Pryodex RS

100––––––––––––––––––––––101.0
110––––––––––––––––––––––113.1
120––––––––––––––––––––––124.2

I would say all of these measurements are accurate to +/- .5 grains

I filled up the measure and leveled the top with a business card.

All were weighed on a RCBS 750 digital scale.
