A two-pronged approach having opposit effects. I started out light with 28 grains/vol. equivalent in the .44 seating to the full extent of the lever-reaching the powder column with slight compression. It was spasmodic. At 35 grains the load found its balance. seating was about half of the loading stem for a "firm" ( whatever that means on any given day) seat on top the powder.
As a matter of interest, Pyrodex P with 28 grains/vol equivalent clocked 848 with 52 fps extreme spread. On other occasions, 35 grof Swiss 3f has driven the same ball to 1089 fpx with 33 fps spread.`
Bates got his spasmodic readings with the heavier 12.5 Grain charge trying firm and then less firm pressure on the loading lever for the two strings. Both sucked. He then followed the exact opposit path I had taken with the .55 and loaded the small Pocket Model chambers with 10 gr/ vol equivalent and the same approximate seating pressure he had used on his first string with the heavier charge. With basically opposit approaches, we arrived at consistent loads and are still confused.
