[Harry Potter] What is the opinion on firearms in the wizarding world?

I remember in one of the books there was a description of a gun and it was almost as if they were describing a caveman savage weapon. Why do they not use them? Do they not realize they could’ve ended their war basically overnight with them?

The gun is a muggle object. It is unrefined, and crude, compared to the elegance of magic.

It also might not work after the first few times. Once you start using it regularly, someone is going to whip up a Responsive Protection Charm bound to their clothing, that would snatch bullets out of the air, or some form of magic that fuses the bullet with the cartridge/barrel, rendering the device useless.
