I want to learn everything (kinda) about guns
A while ago I saw an expert on YouTube comparing the realism of a certain video game's guns, and I was amazed by his knowledge, but I never understood Jack about caliber, models, how they work, components and history. I've been curious for a while, I want to understand more about this topic, do you know any website, book, YouTube channel or something that can help satisfy my thirst for knowledge?
Edit: I posted it before finishing the post.
Edit 2: Some changes to make it simple and understandable.
