- ^The "A/B/C" suffixes for HE rounds are my way to differentiate between projectiles, they were not official designations.
- ^Some of these rounds may have been only for the railway guns.
- ^I believe the reference "Les Materiels de l'armée de Terre Française 1940, pt2" contains typographical errors for both shell weights and muzzle velocities, which I have corrected in this table.
- ^Propellant was in two bags.
