[Spaceships] Conventional and EM Gun ranges in atmosphere?

Are all those quoted damage values for the Spaceships versions including the minimum multiplier for their velocity; IIRC *2 for EM and *5 for Grav?

And some advice I was given from the forum may apply.
A rough estimate, for gaming:
• Muzzle Energy x 4 gives
• Muzzle Velocity x 2 (mv equates to me^0.5)
• Damage x 2.05 (ME^0.52)
• 1/2D range x 1.4 (velocity increase ^ 0.5)
• Max Range x 2 (mv increase = range increase)
Acc +1* (treat this as per Match Grade loads and only add an increase if the original weapon is Acc 4+)

Or if I remembered those damage multiples correctly (*2 & *5):
EM get +40% 1/2D range, Grav get +120%
EM max *2, Grav max *5.
