I've taught many both hobbies in the last few years. Those with interest but don't know where to start I usually start with explaining that I treat it like two separate hobbies one reloading and the other is casting. Then pull out a pocket example of a cast boolit that has been powder coated and explain there are relatively few the actually made the projectiles but quite a few more that reload a cartridge. Next if I feel that if they are the type of person I wouldn't mind inviting to home I do so and will train them if I'm sceptical then I encourage them to play on YouTube and go from there. Good luck and yes it's good that you're trying to help.
