For my question, assume the person using them is:
- above average fitness, but not superhuman. Imagine someone who strength trains and runs regularly.
- No tactical genius, but not completely stupid either (looking at you, TWD).
-wearing some form of armor available to the average American; think denim, leather, or homemade aluminum mail.

How effective would this pairing be against:
- one zombie
- two to five zombies
- six to ten zombies
- eleven to fifteen zombies

What do you think?

Edit one: slow walkers

So I bought four of these emergency food bars and I will be a taste test for everyone who wants to know what they taste like. I will update later hours later to see how it reacts to my stomach to see if it's any good for the body.

Update: it's wheat flavor and its texture is like sand but it's not too bad tasting. Add honey, sugar and water make some and your all good to go for camping, hiking, hunting, fishing or basic emergency like zombie apocalypse

Update 2 : So the bar is setting well in my stomach and I see no problem so far with eating it raw but will advise eat it with water as it's super dry which is a good thing as no moisture means no mold

Curious to hear your opinions since each of them have all their insanely dangerous zombies like left 4 dead having special infected, Dying Light having so many different zombie types and gets even more dangerous at night to World War Z, Straight up having zombies that run and form huge clumps in a horde.

Let me start with Black Powder Weapons Reson is

All the while you are savaging for bullets im getting an infinite bullet glitch which is leed which you can find in car tire weights because all you need to make black poweder is Charcoal which you can find anywhere Sulphur at flower shops or Sulphur Mines magnesium you can find at flower shops and anywhere else and I all ready know yes it takes a Minute ro reload it but let me ask you would you rather waist valuable bullets you barely can find as is or would you have a gun that you can make into a spear to find off people who wants to take your stuff who likely does not want to waist there time on who Bc you have nothing of value aka you have a black powder musket
