For anyone who may be loading 4198 by volume: my current batches of H4198 are much denser than the charts. It is 'supposed to be' a little over 13 grains per cc. But mine is measuring 14.35 gr per CC
my IMR4198 is at 13.05 gr per cc which is not too far off the dipper charts, etc.
I immediately wondered about folks who load this stuff with dippers for the .45/70. Double check with the scale! This could be four+ grains of powder in a big case, when comparing to the Lee dipper chart.
