Would a 40mm round do twice as much damage as a 20mm round?

Precisely.

And a 120mm round would do 10x the damage of a 12.7mm round.

Which is why it takes 10 50cal bullets to kill a Tiger tank.

It would do 4 times as much damage as a 40mm round is 4 times bigger than a 20mm round. This assumes that you can equate area to damage.

Do the math:

The area of a circle is pi times radius squared. Double the radius, as in 20mm to 40mm, and the the area of the larger circle is 4 times the size.

Not true at all. Energy=Mass x Velocity squared. Basically when you double the dimensions of an object its mass is cubed. When you factor these things together a 40mm round traveling at the same velocity as a 20mm round (assuming the shape of the projectile is the same, just bigger) will be much more than double.

Choctaw111,

Your analysis is correct if the length is doubled, but there was no mention of that. Besides, this whole analysis goes out the window if the rounds are explosive, which they probably are. A 40mm explosive round will do much, much more damage than a 20mm round.

I think we all know whom we need to come into this thread and sort it all out.

I just want to see a Twin BF110 with a 88 Flak mounted in between? Does the plane make a jump back when fired?
