So here's how loot works now. 

GM rolls Xd10(X is dependent on the size of the area being looted. There's a basic list on the first page) and each number represents something. Three of the loot types have a double chance of finding(because they are the most common). Guns(and bows and crossbows and whatever) are now just part of this roll, so we're not making a million rolls every time we enter a new space.
