IMR 7828ssc here too. I load it with Berger 210s and 230's in the 300 WSM. 210s run right around 2850 fps, and the 230s run around 2700.I have had very good success using IMR-7828 and 185 Bergers. I achieved just short of 3000 ft/sec and very good accuracy with my load. I have only shot it at targets.
