Olde Eynsford 2F in the .44/90

[Lumpy Grits]

One weird thing I found with Old 'E' 2F. The volume measurement/weight with standard Goex 3F powder. Is the same with 'E' 2F. They even look the same in granulation, except the 'E' is much blacker in color. I load 85 gn in my .45-90 with a PJ Creedmoor bullet.
The last lot of 3F Goex was more towards the very dark gray in color.
My sight settings did not change either.
