I ordered some IMR 700 X from Graf & Sons, when it arrived I was invoiced for 700 X but they shipped 800 X. I have not used it before and was wondering if anyone had any experience with it. I did not send it back because any usable powder now is hard to find. I looked on Castpics and they had no load data listed for any caliber. Hodgdon load data have limited load info for 44 Mag, 45 ACP and 45 Colt. Most were in a single bullet wt.
