They are saying FFG 777 only in cartridges.
What does the loading date indicate in their pamphlet (Hodgdon)? I don't have a Hodgdon loading manual and the manuals I do have are only showing data for smokeless in regards to CAS loads for the 45 Colt - nothing for 777 . . . .
Regardless of "lawyer influence" . . . I think I would pull the loads and dump 'em and follow what the Hodgdon loading manual data indicates . . . some may have used 3F 777 but personally, I sort of like my fingers on my hands. Just my thoughts for what it's worth.
