I never had this problem. What's the first thing you do in any game when you've cleared an area of hostiles? You LOOT THE BODIES! I don't care if it's a shooter, an RPG, or whatever. All gamers should do this automatically, and nearly, if not every time. Do this and you will almost never find yourself out of ammunition, weapons, or supplies. With Mass Effect 2, I only ever had to really ration ammunition or go find ammunition during a shootout once or twice and only on the insanity difficulty.
I agree and this is what I do in games, but there were a few times that bodies left no ammunition. I never completely ran out of ammo, but I ran out of shotgun ammo somewhat regularly.
It also helps to consistently get headshots, I suppose.
