ASM826 is not only a great rifle instructor, he is great at explaining things like reloading. He has a series up that's worth your while, if you've a hankering to try it yourself.
Part 1. Why bother?
Part 2. Getting started
Part 3. Checkpoint: Are you doing it right?
Part 4. Reassess: why bother reloading?
Part 5. Video
Part 6. Casting bullets
Part 7. When it goes wrong, it goes very wrong indeed
It looks like he's still adding to the series, but he's helpfully tagged it for your convenience. Excellent.
I've had the pleasure of reloading with him in his ammunition factory, along with #2 Son. As I said, he's an excellent instructor. If you're considering taking this up, you should spend some time on his posts.
