Some more on weapon interaction:
The guns don't keep track of whether there is a round left in the chamber on reloading or not. This means every time you reload you need to pull the bolt back again. 
Some exceptions are the garand, which automatically closes the bolt on inserting a new clip, the shotgun which autoreloads, and the lever action repeater which never runs out of ammo but has the lever action thing which barely fucking works half the time. I don't know how they would have done bolt actions, if they were in the game.
