Am I right in thinking that the loading data from Hodgon for 777 is black powder volume ? So when it says for a Ruger Old Army to use 35gr what it really means to use the volume of 777 that 35gr of blackpowder would take - so the real weight is going to be something like 26gr as 777 and blackpowder have different densities.
I've seen some loads posted on this forum but its not always clear whether people were referring to volume or the real weight (I think theres a bit of a mix).
