RE: Black powder and black powder suds
Well I guess I am a shooter not a writer I can see I did not make my point.
I do not judge by the volume of the load but by the pressure of the load; it takes close to 140 gr of BH to give you the same pressure as 120 gr of 777 FFF the difference is close to 20 percent or a bit more.
Volume is the way we normally measure so that's the way I am designating but it is not the true limiting factor pressure is. Lee
