Ammunition Range and Effect Questions

[RichardPF]

So in reading over the Standard Rules I came up with some initial questions:

1) Special note was made pf the range differences between the different types of ammunition.
Does anyone know if there are different markings on the ruler for the different ammunition types, or, is it possibly that since there is only one deck of damage cards for each of chain and grapeshot those ammunition types are only effective for the closer marking on the ruler? (as opposed to the ball ammunition which uses the B deck for short range and A deck for long range).

The rules did say that the chain ammunition in particular was more useful with the advanced rules but did say that the player chose from the three when using the standard rules.

2) I see how damage reduces the spread between the a first and second maneuver card. Is this the only way that rigging damage is expressed in the standard rules?
