Whoops, should of been more clear. Yeah, Spaceships 20sec scale. The tanks full mass would be almost all railgun if it fired at ROF 1 heh.
For some reason the point defense guns are in seconds though. Probably should of waited to get some sleep before stating this up heh.

Just ran the numbers again and I made a mistake. 30lbs is how much a round would weigh if it was a full sized medium battery, I forgot to reduce the weight for the round for being very rapid fire! It should weigh only 1.5lbs per shot.
If your interested:
Damage in d-scale from railguns is caliber in centimeters×3. This takes into account that railguns have 2 miles/sec of muzzle velocity.
Caliber is 10^((SM+Gb)/13)
SM is the ships size.
Gb is 8 if a major battery, 7 if a medium battery, 6 if a secondary battery, 5 if a tertiary battery and 9 if a spinal battery.
Divide caliber by two if rapid fire, by 4 if very rapid fire.
Bullet weight is 10^((SM+Gw)/4)
SM is the ships size.
Gw is 12 if a major battery, 13 if a medium battery, 14 if a secondary battery, 15 if a tertiary battery and 11 if a spinal battery.
Divide weight by 5 if rapid fire, by 20 if very rapid fire (or by 4 and 16 if you want to be exact, oh David and your pentaphilia).
Number of shots is 10^((SM+Gs)/6)
SM is the ships size.
Gs is 6 if a major battery, 5 if a medium battery, 4 if a secondary battery, 3 if a tertiary battery and 7 if a spinal battery.
Multiply number of shots by 5 if rapid fire or by 20 if very rapid fire (or as before, 4 and 16).

Sir, they're counter firing!
Right. How much time until the round reach us?
19 minutes sir!
Very good. Plenty time for tea.
