^^^ About that "nail gun", I have a device that drives nails into concrete. It uses a .22 blank cartridge to "shoot" a nail with a plastic sabot.
History: I have been a gun guy for decades. I have had .22 pistols, revolvers, and rifles. Fun stuff. I have shotguns and rifles, some bolt action, some semi-auto. I once caught a copper jacket from a ricochet. In the neck.
That being said, that nail gun (*) is scary. I wore gloves and safety glasses. And I think I would rather use a hammer drill and concrete anchors than use that infernal device from hell.
(*) I don't mean a "nail gun" like my Bosch framing nail gun. It is great for framing.
