I figured rubber meets the road and tested with ball powder to the top.
Tiny grains, clean sweep off.
I wrote it down someplace,e pretty tiny.
I just treat all brass the same, don't start at max, 5 to 10% lower than the lowest max (assumes I don't start lowest listed anyway)
I ran some data the other day on R17. Aliant does not show low loads, just say 10%,
Hornady that does list R176 and min to max, it was 16% spread.,
