Well no you're not wrong. It's definitely not a linear formula. If propelling a 1kg shell at 1000m/s takes X propellant. it is definitely more then X2 propellant to propel a 2kg shell at 1000m/s
The point where you go off the rails a bit is that it's mass, not volume or diameter that makes the difference. If you used the same diameter bore, and a denser shell, you'd see the same results.
Ah yes. In any case, would take lots more propellant, which a 'Mech may not have space for such large round and would explain the lesser range.
