On another site, there's a member trying to learn about firearms, and I was trying to find a source of basic information for her. Maybe a website with articles that explain how guns work, different types of guns, gun laws in America, etc. I've found a number of sources for legal and political information, but where could I send someone for basic knowledge (what a cartridge is, difference between semi-auto and full-auto, etc)?
I've checked the NRA website, the NSSF, TFL, and I'm surprised I'm coming up empty.
