I set my loads .3 grains apart. For 123gr pills I see 25 +/- fps spread per .3 grain charge, then when I get a velocity node, that drops to single digit velocity spread between .3gr increments. Same theory should apply here, different speed spread.
So, I have 2 nodes in that first run, and all the case heads looked fine after closer inspection, so with the seating longer, I may run up to 33+ grains of CFE. Still worried about temp sensitivity. Though, the 2450 is my target speed. Would like to see a bit more, but that is running a touch slower than Hornady Black in the same rifle.
