Nice - 2400 is fun & snappy no doubt., and yes on the N frame. 
My latest chrono data (.44 mag "lite") shows 15.3 gn 2400 w/ a 240 gn LSWC (Hi-Tek coated) had a mean right at 900 fps over 24 shots (629 w/2-5/8"). I hope to do the same set with the 329PD shortly. Accuracy was also pretty good - hitting 10" gongs ~4/5 at 50'
Our local shop here just got a big Alliant delivery, so I snagged a few bottles of 2400 before they 'evaporated'.
