I know this is an older thread, but in case anyone stumbles upon it I did try this Hogden CFE Pistol powder this past week.
In 9mm with a 124 gr Montana Gold bullet seated 1.15 OAL I got the following
3.8 gr averaged 805 giving a PF of about 100 - this did not function the 4" XDs well at all, many stove pipes
5.2 gr averaged 1004 giving a 124 PF and SD's around 10 - function in the same 4" XDs was fine with no problems.
I think the "Copper Fouling Eliminator" is mostly marketing but the powder was reasonably priced ($24) and seemed to work well. There seemed to be less flash and smoke than Alliant Power Pistol but that has worked well for me also
