"Also how strongly do people agree with these generalizations?
1. Ball powder fouls significantly more than extruded powder.
2. Ball powder meters so much better than extruded powder that I would only use ball powder for metered loads when I care about accuracy."
1. Not the ball powders that I use.
2. Different uses, different powders and types. In general ball is easier to dump with a measure but not always. I always care about accuracy.
