This is the last manual from IMR to give load data for IMR 4227 in most major rifle calibers. http://www.castpics.net/LoadData/Freebies/RM/IMR/IMRHandloadersGuide.pdf It is from May 2003.
Perusing this data set, I see data given for 44 Mag with 3031 powder. I don't remember ever seeing that before. (ETA: page 50)
Even more strange, it shows data for 44 Mag with 4198, past 4895, and on through to 4831. Interesting to see how the pressure and velocity drops off with each progressively slower powder.
Although I have heard of folks trying 4895 in 44 Mag, I never even thought about 4350 or 4831.
