Well, a bit of Google-phoo tells me that the .44RF fired a 200gr Flatnose with a BC of about .153 at about 1125fps...
JBM Ballistic's maximum range calculator tells me that, at 80F, 25% Humidity and 0ft altitude, the maximum range would be 1963 yards, fired at a 35% angle.
I'll figure the other in minute or three...
