How does weapon XP work?

[youngie197]

E.g. do you get more XP for higher difficulty hit with a bow? (ie further away, faster moving?).
Does damage done have any effect on the amount of XP gained? ie is a hit a hit, or does doing 200 damage give you more than 10?
Is there a headshot XP multiplier etc?
Does enemy level have any effect?

I don't know how it work's with damage or enemy lvl. But the dificulty affects the Xp. So it would make sense that a headshot increases the difficulty of the shot (but i havn't tested it)
