Along the same lines...
Many folks get tripped up between FFG and FFFG powders when it comes to loads.
As FFFG (3FG) is finer granulation, an 80gr load of 3FG is closer to 90gr FFG (2FG) in energy.
At least 10% reduction in Max load should be factored when shooting 3FG powders using 2FG load data. This is my rule, not any written guideline.
