I really dislike that phrase "loaded a case full of black". It does make it sound like a case is filled flush to the case mouth.
If you did fill that much powder you would be compressing the powder column down more than a quarter inch.
I doubt that much compression is possible without splitting the case side.
I have loaded 35 to 38 gr. of 2fg & 3fg with the new version of the Lyman 452664 and the lube groove is more than adequate for any length revolver barrel. I even shoot that bullet in a 24” Win 73 rifle.
This is going to be interesting. All I have is GOEX 3F and Olde Eysnford 3F. What I always liked is a grain weight load, instead of load then crunch. Seems more repeatable that way, even though my New Model Army will not exactly be a target pistol. I might also experiment with some home made black powder loads, too.
