I've just been here for maybe a week now but I've encountered some issues with the current system, I'm not sure if they are bugs or intentional features.

The first time I attacked a zombie with a ranged weapon, I used a bow and had five arrows in my inventory.  The dialogue I received from the fight didn't say anything about missing, and the hunting section on here says "Hunting your prey with a firearm may take up to 3 bullets, depending on your aim skill, experience, and luck." but all five arrows were shot.

The next time I used a shotgun, having four shells the situation happened the same and 100% of the ammunition I had for the weapon was fired.

In both cases, the defeated zombies said they would be looted, but nothing appeared.

I have also defeated two zombies with hand weapons, also no loot.

From a HUD perspective this really doesn't make any sense.  Within the HUD, the player has a choice of running away with 100% certainty of success, or they can fight and risk health, spend valuable ammunition, and have a small chance of reward.  My little venn diagram between the options doesn't have any balance unless this is all bugged.
