There is considerable talk that the new Alliant 2400 is "hotter" than some of the older lots of Hercules 2400. and even that more recent lots of Hercules 2400 is hotter than the original powder. This particular can was kept in a temperature controled environment since the 1970s. The revolver used was a 6" GP100 with temperature at 45 degrees F.
The measure throws 14.2 Herc 2400 when set for 14 grains of Alliant. it is unknown if this is because of differences in original manufacture or a result of age. In any case, I clocked 12 round strings with 14.0 of both powders and 14.2 of the Hercules.
