has anyone tested FFF vs FF in the loose powder 777. I have been using FFF 777 but recently noticed the store now only stocks the FF version of 777.

I have never tested the two types side by side. I went with FFF after e-mailing Hodgdon a few years back, asking why FFF produced more velocity. Here is what Mike Daly of Hodgdon had to say in response to my e-mail.
Hope this helps,

you get more velocity from 3F than 2F because there is more fuel in the same volume with the finer particle size. 3F is also faster burning than 2F.

If you want to get the very fastest velocity possible, 3F is the way to go.

I use 3F T7 cuz I can use a little less of it to get the same velocity, they both cost the same, just $$ sense. It's just as accurate in 3 different inlines.

I tested both side by side in my encore. 105 grains of 2f will group about 1 1/2 inches. 3f shrinks to about 3/4 inch. I find it easier to measure as well.

I got roughly the same results as upnorth by switching to 3f. Ironically it was by accident!! I dropped my 2f load by ten grains and my group size dropped also. Good luck!!
