What is the ballistic range for TR and NC?

[Mihn]

Just curious, I saw that there is bullet drop over distance which prompted two questions:

1) If I fire a tank shell at someone on top of a hill and miss (too high). How far would that shell travel? Presumably it could go quite a distance and potentially hit someone kilometers away (which would be cool).

2) If I shoot a bullet vertically will it eventually slow to a stop, fall back to the ground gaining speed all the while, and then kill me?
