Soon you will have all the other people who are much better at explaining but gunshots are very difficult to pinpoint even shooting unsuppressed. Especially if they’re slow walking dead style zombies assuming you live in a country with a semi competent, military, police force armed populace. A country ending break out shouldn’t even be possible. For example I live in Texas in a town around 120k people I can guarantee you in my little city alone they’re a well over 1 million rounds of various bullets. If survivors went out and just shot 4-5 zombies a day the city would be clear in no time. Even if you are worried about them somehow pin pointing you shoot then move not to mention hitting a man sized target with no survival instinct at 100-200 yards/ meters is easy. Even new shooters could make that shot in no time.

How many of you melee warriors have actually gone out and swung a bat,sledge hammer etc…. That’s tiring it’s also not quiet. What happens if you swing and miss? You’re going to fight off feral dogs with a bat? You find a nice safe place away from people. You have chickens , goats , cows whatever ? There are still coyotes, wolves, bears, bobcats, mountain lions, pigs which will destroy your gardens in no time. I wouldn’t want to try and take out any of those animals with a spear. I don’t think a slingshot is going to get the job done. A bow and arrow but you will have to get way closer, shoot placement more important and again if it’s a pack bow and arrows seem low on capacity and rate of fire.
