History (or any other subject) was not my strong suit in school.

Interesting topic. I filled a fixed volume charger full without tapping and weighed 3 loads.
4f weighed 59.7 g
3f weighed 58.5 g
2f weighed 54.5 g
I was taught the highly scientific method (60 years ago), if it pops too little, if it booms too much, if it cracks probably about right.

Not surprising on the heavier weight of the finer powder. It’s like the old teacher example of filling a jar with rocks and asking the students if it is full. Yes is the answer. Then the teacher adds sand. Is it full now? Yes! Last the teacher adds water to the jar. There is more air space between coarser powder grains.
