I just compared two 2400, two Uniques and two Power Pistol rounds out of a 4 inch revolver.

One thing I noticed was....unique produced so much smoke that I actually had to step to the side out form behind a cloud of smoke to see what I was shooting at.

Of course it was mild compared to black powder from a ball and cap...but good grief, I thought smokeless was supposed to be just that. Power Pistol and 2400 had almost nothing in the air after discharge
