IMO, 2400 is far more useful than H110/296. Its flexible in that it can be shot at less than near-max to max pressure. I like IMR4227 for the same reason.
I use H110/296 in heavier bullet (160gr+) cast and 110gr jacketed 300BLK loads, but had used it in heavy cast bullet 357mag carbine loads in the past.
