Every time you load a saved game, the chests and lootable objects restock. Save 
the game near a place where there are multiple weapon chests, such as in the 
town of New Haven. Collect all the loot in them, then save the game. Reload the 
saved game, and collect all the loot again. Keep the loot you want, and sell the 
loot you do not want. Repeat this as many times as desired. Note: You get more 
money and better loot when there are more than one player. This is best done 
with four players.
