You also have to take into account the gases (and particles) ejected from the muzzle.
You’re right!
Assuming that all of the powder reacts and is ejected from the muzzle, I suppose that the ratio should be relative to the inertial mass of the cartridge minus the inertial mass of the casing.
I suppose that, since the question posed was for a 45, one also has to take into account the ejection of the cartridge as well.
