That's been my experience also across several BP cartridges.

Using a smokeless kicker isn't 'proper' to some (and I am usually big on 'proper'), but the lessened fouling makes up for that in many ways - hunting, especially, and regulating a double.

The target guys will wipe between shots just like they did back in the late 1800s so fouling isn't a big issue; to those people, the best accuracy obtainable is the goal.
