Conversion of propellant charges

Conversion of propellant charges. Sections
This section collects information on the conversion of propellant charges for 155 mm guns:
how the old bagged charges relate to modern modular systems, their weight, length and propellant grade, temperature ranges and limitations.
This is an approximate comparison, not a guide to action.
Modular propellant charges are not absolutely identical to one another, so we analyse their parameters to assess range deviations when the propellant charge is changed.
