Still haven't learned. I just punch out the old primers, fill the case up with any powder I find and if the case holds a certain bullet, I'm good to go! 
Actually, my dad and grand dad. When I was 5-6 years old I would help dad load 38 Specials. By the time I turned 11 I was loading shotgun. dad's attitude was if i shot it I had to learn to load it. I went to 30-30 and 30-06 followed by 357. I started casting bullets when I was 12-13.
In another post, I commented that last June I celebrated loading the 44M for 50 years. I got my first S&W M29 in 1962.
Dang, I'm getting old.
