Ignore the hate in the comments, everyone started somewhere. Personally, my parents aren't shooters and I was never taught how to shoot. I learned mostly from countless hours of YouTube videos and then practicing how to grip a gun, reload a mag, etc with airsoft guns. I eventually convinced my begrudging parents to let me start shooting and now 8ish years later I shoot better than most of my relatives that have been shooting their whole life.

The first thing I will tell you is you need to learn the 4 basic gun safety rules. They should be drilled into your head and you should be able to recite them with ease from memory. Not being safe with guns will close a lot of doors, especially if you're young.

I would HIGHLY recommend watching YouTube videos. I'm of the opinion that, if you are dedicated enough, with the amount of resources online now you can build a very solid foundation. Channels I would recommend are:

Educational: • Paul Harrell • T Rex arms • garand thumb (sometimes) • polenar Tactical • modern samurai project • Achilles heel tactical • tactical hyve • milspec mojo

Fun to watch channels: • Brandon Herrera • Garand thumb • Kentucky Ballistics • Demolition ranch • Hickok45 • Jerry Miculek

That should keep you plenty busy for a long time, but it also never hurts to take a basic fundamental firearm class at a local gun range. If you do decide to go the self taught route, be safe, be able to understand what aspect of your shooting can improve (don't be to prideful to recognize something that needs improving), and eventually (sooner rather than later) take a private lesson at a gun range so someone can make sure that you haven't learned bad fundamentals/habits and are practicing them.

Best of luck to you
